What's the best gravel for a driveway? Compare types, learn the right depth (4–6 inches), and follow our step-by-step installation guide. Includes driveway ideas and cost calculator link
The complete guide to choosing, installing, and designing a gravel driveway — from six material comparisons to a proven three-layer system.
Last updated: July 2025If you want the short answer: crusher run (also called road base or crush-and-run) is the best gravel for a driveway in terms of stability, longevity, and cost. It compacts to a hard, near-paved surface that resists shifting and washout far better than any other material. For driveways where drainage is the priority, #57 crushed limestone stone is the top choice — its angular shape interlocks while still allowing water to pass freely.
This guide covers everything you need to plan and build a gravel driveway: the six main driveway gravel types compared side by side, the correct three-layer system (sub-base, base course, surface) totaling 10–14 inches, a complete 7-step gravel driveway installation guide targeting both DIY homeowners and those hiring a contractor, and design ideas for modern and contemporary gravel driveways that add genuine kerb appeal.

The best gravel for a driveway is crusher run for stability or #57 crushed stone for drainage. These are the two materials you should consider first for any residential driveway. Pea gravel, while attractive, is the worst choice for driveways — its rounded shape doesn’t interlock and it scatters aggressively under vehicle traffic, making it a poor primary driveway surface material regardless of how much edging you install.
The best type of gravel for driveway use depends on three factors: your climate, vehicle traffic load, and aesthetic preference. Here is how the six most common driveway aggregate materials compare:
| Gravel Type | Size | Cost/Ton | Stability | Drainage | Best For |
|---|---|---|---|---|---|
| Crusher Run / Road Base BEST | Mixed fines to 3/4″ | $20–$45 | ★★★★★ | ★★★ | Driveways, base layers |
| #57 Limestone Stone | 3/4″–1″ angular | $35–$55 | ★★★★ | ★★★★★ | Driveways, drainage |
| 3/4″ Crushed Gravel | 3/4″ angular | $30–$50 | ★★★★ | ★★★★ | General driveway |
| Crushed Limestone | 3/4″–1″ | $30–$50 | ★★★★ | ★★★★ | Midwest/South driveways |
| Decomposed Granite (DG) | Fine granular <1/4″ | $30–$70 | ★★★★ | ★★ | Dry climate driveways |
| Pea Gravel NOT RECOMMENDED | 3/8″ rounded | $25–$50 | ★ | ★★★★★ | NOT recommended for driveways |

Crusher run — also called road base, crush-and-run, or processed gravel — is a mixed gradation of crushed stone containing both coarse angular pieces up to 3/4 inch and fine stone dust. That combination is exactly what makes it exceptional: the fines fill the gaps between the larger pieces and bind together under compaction and moisture, creating a dense, hard-pack gravel surface that behaves almost like a paved driveway. It is widely available across the United States, the cheapest effective driveway material per ton, and the easiest to compact solidly.
The main trade-off is appearance — crusher run is a utilitarian grey-brown and generates dust when dry. It is not the most decorative option. But for a functional, long-lasting, hard pack gravel driveway surface, nothing comes close for the money. This is the material used under asphalt and concrete for the same reason it performs well as a standalone driveway surface: it locks together structurally.
#57 stone is the most widely available driveway stone in the United States — it is what most landscape and stone suppliers mean when they say “driveway gravel.” The angular shape produced by crushing means the pieces interlock under vehicle pressure rather than rolling freely. Drainage is excellent because the uniform sizing leaves open voids for water to pass through. The classic grey limestone colour suits most residential settings.
#57 stone costs more than crusher run per ton and scatters more easily if the driveway is not properly edged. It is the right choice for driveways in high-rainfall areas where drainage is as important as stability, or for homeowners who want a natural stone appearance rather than the hard-packed look of crusher run. It is also the standard material for the base course (middle layer) in the three-layer system.
Standard 3/4-inch crushed stone (often simply called “crushed gravel” or “crushed rock”) is functionally very similar to #57 stone and is sometimes used interchangeably depending on regional naming. It compacts reasonably well, drains effectively, and provides a reliable middle-ground between maximum stability and maximum drainage. It is available in limestone, granite, and other crushed stone varieties depending on your region.
This is a solid choice for general driveway use where you want a product that performs well on all criteria without specialising in any. It works well as both the base course layer and the surface layer in a full three-layer driveway build. The driveway gravel material cost is competitive, making it a good-value option for large driveways.
Decomposed granite is crushed granite that has broken down into fine granular particles, typically under 1/4 inch in size. When moistened and compacted, DG binds firmly and creates an attractive warm tan surface. It is extremely popular in California, Arizona, and Texas, where the dry climate suits it perfectly and the colour complements regional architecture beautifully. It is a strong contender for the best stone for a gravel driveway in dry regions.
The critical limitation is rain — DG erodes significantly in heavy or sustained rainfall. In wet climates (Pacific Northwest, Southeast, Northeast), DG washes into channels and gutters and creates muddy puddles. In those regions, use a stabiliser additive mixed with DG, or choose crusher run or #57 stone instead. Stabilised DG costs more but performs far better in moderate-rainfall environments.
Crushed limestone is functionally identical to #57 stone in most applications and is the same material in many regions — #57 stone is frequently made from crushed limestone. It is the dominant driveway aggregate in the Midwest and South United States, where limestone quarries are abundant and the material is highly affordable. Angular crushing ensures good interlocking under compaction.
If you are in a region where crushed limestone is the cheapest available angular stone, it is an excellent choice for all three layers of the driveway build. Performance is essentially the same as #57 stone — use whichever is cheaper and more readily available from your local landscape supplier.
Pea gravel scores highest for appearance — the small, smooth, rounded pebbles come in attractive earth tones and feel comfortable underfoot. It is widely available and relatively affordable. However, those same rounded shapes that make it attractive are precisely what make it a poor driveway material: rounded pea gravel has no interlock. Each stone rolls freely under tire pressure. Vehicles spin wheels in it, push it to the edges, and create ruts and bare patches within weeks of installation.
No amount of edging fully solves the problem because the issue is the physics of the stone shape, not just lateral spread. Pea gravel belongs in garden paths, decorative beds, playground surfaces, and around drainage areas — not on driveways where vehicles park, turn, or accelerate. If you want a fine, attractive gravel surface for a driveway, decomposed granite with a stabiliser is a far better choice that still has visual appeal. For the best gravel for driveways that wash out, avoid pea gravel entirely — use crusher run or #57 angular stone.
For driveways that wash out in heavy rain, use crusher run as the compacted base topped with 3/4-inch angular crushed stone as the surface layer. The angular shape of both materials creates mechanical interlock that resists water movement. Never use pea gravel or smooth river rock — rounded stones have no interlock and wash away immediately in moving water. Equally important: the 2% crown shape from centre to edges (described in the installation section below) is essential for preventing washout by directing rainfall off the driveway surface rather than channelling it along the length.
A properly built gravel driveway has three distinct layers totaling 10–14 inches. Skipping the sub-base or compaction steps causes the most common driveway failures: rutting, washout, and uneven settling.
A new gravel driveway should be 10–14 inches deep total, built in three compacted layers. For top-dressing an existing driveway with new surface gravel, 3–4 inches is the minimum effective depth — anything less will show bare patches within a single season of use.
How thick should a gravel driveway be? The answer depends on whether you are building new or refreshing an existing surface:
| Layer | Material | Depth | Notes |
|---|---|---|---|
| Sub-base | Large angular stone (3″+ size) | 6″ compacted | Structural support and primary drainage |
| Base course | #57 stone or 3/4″ crushed | 4″ compacted | Transition layer and load distribution |
| Surface layer | 3/8″–3/4″ gravel or DG | 2–4″ | Driving surface and appearance |
| Total (new build) | All three layers | 10–14″ total | From excavation to finished surface |
| Top-dressing only | Surface material only | 3–4″ | Existing driveway refresh — minimum effective depth |
Depth data: Last updated July 2025. Depths are for standard residential passenger vehicle traffic.
The standard 6-inch compacted sub-base is the minimum for passenger vehicles and light trucks. For heavy truck traffic, delivery vehicles, or commercial use, increase the sub-base to 8–12 inches of compacted angular stone. Do not use rounded river rock or pea gravel for the sub-base under any circumstances — rounded stone does not lock under compaction and shifts under load.
The base layer for a gravel driveway is the most important element in the entire construction, and it is the layer most often skipped by inexperienced installers trying to reduce cost. The sub-base is the critical structural layer that prevents rutting, sinking, and rapid deterioration. Use angular class 2 base rock or large crusher run for the sub-base — these materials lock together under plate compactor pressure and create a stable platform for the layers above.
Coarse gravel for driveway sub-base and base layers should always be angular, not rounded. Angular stone interlocks mechanically under compaction; rounded stone rolls and shifts. This is why #57 stone and crusher run outperform pea gravel and river rock structurally — the crushing process creates angular fracture faces that grip each other.
Compact each layer with a plate compactor before adding the next. The sub-grade soil itself should be compacted before any stone goes in. Each layer should not shift or give underfoot once properly compacted — if it does, make another pass with the compactor before proceeding.
Hard pack gravel is not a product name — it is the result of the right process. Crusher run becomes almost concrete-like (a true hard-pack gravel surface) when compacted in the correct moisture conditions. The stone dust in crusher run acts as a binding agent when damp. Water the surface layer lightly before the final compactor pass and you will end up with a firm surface that resists scattering and washout far more effectively than loose aggregate.
Adding a geotextile landscape fabric between the compacted sub-grade and the sub-base prevents fine soil particles from working upward into the gravel layers over time — a process called “pumping” that gradually softens and destabilises the base. This one addition extends driveway life significantly and costs very little in materials.
Building a gravel driveway is a manageable DIY gravel driveway project for most homeowners with the right equipment and a clear method. The key steps are excavation, grading, layering, and compaction — done strictly in that order. Skipping steps or reversing the order is the most common cause of early driveway failure. This guide covers how to build a gravel driveway, how to construct a gravel driveway on any residential lot, and how to put in a gravel driveway as a DIY project.
Mark the driveway perimeter with stakes and string line before any excavation begins. Confirm your width — standard residential is 10–12 feet for a single lane and 20–24 feet for a double lane. Check your local planning codes for setback requirements from property boundaries and road easements, and check whether your municipality requires a drainage permit for new driveway installations. At this stage, calculate your material quantities for all three layers separately — use the free Gravel Calculator at everycalcpro.com/calculator/gravel-calculator/ to get accurate cubic yards and tons for each layer before placing your supply order. Ordering all three layers at once and specifying delivery sequence (sub-base first) saves time and re-staging.
Excavate to a depth of 10–14 inches across the full driveway footprint. Remove all topsoil, roots, vegetation, and organic material — organic material is structurally compressible and continues to decompose underground, causing surface depressions and dips years after installation. Do not leave any organic layer in the sub-grade. Grade the sub-grade surface with a 2% crown — highest at the centreline, sloping toward each edge — using a long level or laser level to verify the gradient. This crown shape is essential for directing rainfall off the driveway surface rather than allowing it to pool or channel. Once graded, compact the native soil thoroughly with a plate compactor, making multiple overlapping passes. If the native soil is soft clay or highly saturated, allow it to dry before compacting, or consult a geotechnical professional about subsoil stabilisation.
Install steel, aluminium, or heavy-duty plastic landscape edging along both sides of the driveway before any gravel is placed. Edging is a structural component of the driveway, not a decorative afterthought — it physically contains the gravel and prevents lateral spread under vehicle tyres. Drive edging stakes into the ground at 18–24 inch intervals for firm retention. For a standard residential driveway, steel edging is the most durable long-term choice. Plastic edging is acceptable for lighter-use driveways with smaller gravel sizes. For decomposed granite or fine gravel surfaces, heavy-gauge steel or aluminium edging with deep-set stakes is essential — finer materials migrate more aggressively than coarse stone. Ensure edging stakes are angled slightly outward to resist the lateral pressure of vehicle traffic.
Spread the sub-base material — large angular stone of 3 inches or larger diameter, or large crusher run — evenly across the full driveway width to approximately 7 inches of loose depth, which compacts to approximately 6 inches. Work in sections of 10–15 feet at a time rather than spreading the entire load at once. Use a skid steer bucket or a landscaping rake to distribute evenly. Optionally lay geotextile landscape fabric over the compacted sub-grade soil before adding sub-base stone — this prevents soil migration into the gravel layer over time. Once spread, make multiple passes with the plate compactor until the surface is firm and does not shift underfoot. This layer performs all the structural load-bearing work — it must be adequately compacted before the base course goes on top. This is the stone for driveway base that determines the long-term stability of the entire structure.
Add approximately 5 inches of loose #57 stone or 3/4-inch crushed stone (compacts to 4 inches) over the compacted sub-base. Spread evenly with a skid steer bucket or landscaping rake, maintaining the 2% crown profile. Make sure the base course material is distributed consistently across the full width — thin spots create weak points that compress into ruts under vehicle loads. Compact thoroughly with the plate compactor, making a minimum of three overlapping passes in alternating directions. The base course is the transition and load-distribution layer: it bridges the rough large-stone sub-base and the finished driving surface above. A well-compacted base course is what prevents the surface layer from sinking into the sub-base under vehicle weight over time.
Add 3–4 inches of your chosen surface material — crusher run fines, 3/8-inch angular stone, 3/4-inch crushed stone, or decomposed granite — over the compacted base course. Spread evenly, maintaining the crown profile. The surface layer is what vehicles drive on every day and what gives the driveway its finished appearance. For crusher run as the surface layer: spread to depth, water lightly with a garden hose until the material is damp throughout, then compact firmly with the plate compactor — the moisture activates the binding properties of the stone dust and the surface sets almost like concrete as it dries. For loose gravel types (#57, 3/4″ crushed): compact lightly with one or two compactor passes to seat the stone without fully locking it — leaving some surface looseness allows small rocks to self-adjust under traffic and aids drainage. For decomposed granite: compact firmly when damp, using a vibratory roller if available for the most uniform surface.
After the surface layer is placed and compacted, verify the finished surface has a clear 2% crown from the centreline to each edge. Use a long level or string line to check — the centre should be approximately 1/8 to 1/4 inch higher per foot of width than the edges. This is not a dramatic slope; it is subtle but critical for drainage. Fill any low spots with additional surface material and re-compact. Check the crown along the full driveway length, not just at one cross-section. Allow the completed driveway to settle for 1–2 weeks before heavy vehicle use — the layers need time to compress and consolidate under their own weight and weather exposure before taking significant load. Mark the edges with temporary stakes or caution tape during this settling period. The driveway will continue to firm up and stabilise over the first month.
The key to a solid, non-shifting gravel driveway is threefold: use angular stone (never rounded), maintain proper three-layer depth, and compact each layer thoroughly before adding the next. Crusher run becomes almost concrete-like when properly compacted and lightly wetted. Add a geotextile landscape fabric between the sub-grade and sub-base to prevent fine soil particles from migrating upward into the gravel layers over time — this single addition significantly extends driveway life. For the best results on how to make a gravel driveway solid by hand: work in small sections, compact frequently, and never rush the layering sequence.

A well-designed gravel driveway adds significant curb appeal at a fraction of the cost of asphalt or concrete. The design approach determines the gravel type, edging style, and whether to add landscaping borders or architectural elements. Whether you want a classic residential look or a contemporary gravel driveway with clean architectural lines, the right material and layout choice makes the difference between a functional surface and a genuine landscape feature.
A straight run from street to garage using uniform crusher run or #57 stone is the most common and reliable residential gravel driveway design. Simple steel edging on each side keeps the gravel contained without adding visual weight. Add gravel driveway landscaping on both sides — low-maintenance ornamental grasses, river rock borders, or mulched planting beds complement the stone colour beautifully. This design suits any home style and works in all climates. It is the simplest install and the easiest to maintain over time.
A defined border of larger accent stone, Belgian block, or concrete edging around a central decomposed granite or fine gravel surface creates a clean, architectural look popular in modern gravel driveway designs. Use decomposed granite in tan or buff for a warm contemporary palette. Flanking grass strips or low architectural groundcover on each side reinforce the structured, intentional look. Keep border plants low — compact ornamental grasses or low hedging works best. This modern bordered design is one of the fastest-growing contemporary gravel driveway styles in residential landscaping.
Two parallel gravel lanes separated by a central strip of low groundcover, grass, or native plants creates a striking contemporary gravel driveway effect. Works best with decomposed granite on each lane — the warm earth tone contrasts beautifully with the greenery of the central strip. This gravel driveway design requires precise edging on four sides of each lane to contain the fine material. It is an architectural statement suited to mid-century modern and contemporary-style homes where the driveway is a deliberate landscape design element rather than a utility surface.
Combining a crusher run base with a surface layer of contrasting decorative stone creates visual depth. Use border pavers or cobblestones at the gravel driveway entrance for a formal entry statement. Stone driveway ideas that mix materials — such as limestone chip surface with granite cobble edging — require careful drainage planning to ensure no water pockets form between material transitions. This approach delivers the visual appeal of a formal stone driveway at a significantly lower cost than full paving.
A formal gravel driveway entrance with flanking stone posts, lanterns, and low hedges creates strong kerb appeal and a clear sense of arrival. Use a larger, lighter stone — white limestone chips or pea shingle — at the immediate entrance zone for visual contrast against the main driveway material. The entrance treatment functions as a design marker that signals the boundary between public street and private property. For longer driveways, this entrance design also provides a natural location for drainage infrastructure such as a culvert or swale.
Contemporary gravel driveways increasingly feature: clean steel or aluminium edging (not plastic), contrasting border materials such as Belgian block or concrete pavers at the entrance, integration with permeable paving strips for parking bays, and intentional planting beds along the edges with drought-tolerant species. Modern gravel driveway ideas frequently appear in architectural landscaping for mid-century modern, Scandinavian-influenced, and minimalist contemporary homes — particularly in California and the Pacific Northwest where gravel driveway landscaping is a mature design tradition.
Three common gravel driveway design styles. The classic straight design works for any home. The modern bordered style suits contemporary properties. The split design with a centre strip is an architectural statement — and a strong example of modern gravel driveway landscaping ideas.
Crusher run (also called road base or crush-and-run) is the best gravel for driveway stability and value. It is a mixed gradation material — angular pieces up to 3/4 inch combined with stone fines — that compacts to a near-solid, hard-pack surface. For drainage-focused driveways, #57 crushed limestone stone is the top choice, providing excellent water percolation while its angular shape still provides good interlock and stability. The best type of gravel for driveway use ultimately depends on your climate, traffic load, and whether you prioritise drainage or maximum firmness. In wet climates, #57 stone or 3/4-inch crushed angular stone are the recommended gravel driveway materials. In dry climates, decomposed granite is also an excellent option.
A new gravel driveway should be 10–14 inches deep total, built in three distinct layers: a 6-inch compacted sub-base of large angular stone, a 4-inch compacted base course of #57 stone or 3/4-inch crushed stone, and a 2–4 inch surface layer of your chosen finish material. The total excavation depth before any gravel is placed should be 10–14 inches below finished grade. For simply top-dressing an existing driveway with new surface gravel, 3–4 inches is the minimum effective depth. How thick should a gravel driveway be for the surface layer alone? A minimum of 3 inches after compaction — under 2 inches will show bare patches quickly.
Calculate gravel quantity using the formula: Length (ft) × Width (ft) × Depth (ft) ÷ 27 = cubic yards. Multiply cubic yards by the material’s tonnage factor (crusher run: 1.51 tons/CY; #57 stone: 1.42 tons/CY) to get tons. For a standard 100-foot by 12-foot driveway with a 4-inch surface layer, you need approximately 15 cubic yards or 21–22 tons of surface gravel. Calculate each of the three layers separately because they use different materials and depths. The easiest way to get accurate quantities, tonnage, and estimated cost for all three layers is to use the free Gravel Calculator at everycalcpro.com/calculator/gravel-calculator/.
To make a gravel driveway solid, use angular crusher run as your primary surface material — never rounded gravel. Excavate to the full 10–14 inch depth and build up all three compacted layers in sequence. For the surface layer: spread crusher run, water it lightly with a garden hose until damp throughout, then compact firmly with a plate compactor. The moisture activates the binding properties of the stone dust in crusher run, and the surface sets almost like concrete as it dries — creating true hard-pack gravel. To make a gravel driveway solid by hand (without machinery): work in small sections of 4–6 feet, compact aggressively with a manual tamper, water each section, and compact again. It takes significantly more effort but achieves a similar result for small areas. Adding geotextile landscape fabric under the sub-base prevents soil migration that softens the base over time.
A properly built gravel driveway with all three layers correctly compacted lasts 10–30 years with basic maintenance. Annual maintenance consists of re-grading to restore the 2% crown shape — driveways flatten and develop ruts over time as gravel is displaced by vehicle traffic. Every 3–5 years, add a top-dressing of 1–2 inches of fresh surface gravel and compact lightly. Driveways built without a proper sub-base, without edging to contain the material laterally, or without the drainage crown deteriorate significantly faster — often showing rutting and material loss within 2–3 years of installation. The single biggest predictor of driveway longevity is whether the sub-base layer was installed and properly compacted.
For the driveway surface layer, 3/4-inch angular crushed stone is the most reliable choice for most homeowners. It is large enough to resist scattering under tire pressure but small enough to provide a reasonably smooth, comfortable driving surface. For a more decorative finish, 3/8-inch angular stone or decomposed granite works well in dry climates. Avoid stone larger than 1 inch for the surface layer — larger stone is uncomfortable to walk on, shifts noticeably under tires, and makes the driveway surface feel unstable. Avoid rounded stone of any size for the surface — the lack of angular interlock means it will scatter under vehicle loads regardless of stone size.
No — pea gravel is not recommended for driveways. Its small, smooth, rounded shape means it has zero mechanical interlock between stones. Under vehicle tire pressure, each pea gravel stone rolls freely, causing the driveway surface to scatter laterally, create ruts in the wheel tracks, and expose the base layer. Tires spin in it, vehicles sink when turning, and the material continuously migrates to the edges and onto adjoining lawn or pavement. Heavy edging helps contain the lateral spread but does not solve the fundamental problem of stones rolling under load. Pea gravel is well-suited for garden paths, decorative ground cover, play areas, and drainage beds — applications where vehicle traffic is not a factor.
Crusher run is the cheapest effective driveway gravel at $20–$45 per ton depending on region. It also delivers the best structural performance of any driveway material, which makes it the highest-value option by a clear margin. Bank run gravel (unprocessed gravel from excavation) and recycled crushed concrete can be even cheaper in some regions and perform comparably as sub-base material. Pea gravel and some decorative stones cost more per ton than crusher run and perform significantly worse as driveway surfaces — meaning spending less on crusher run is smarter both financially and structurally. Always price materials locally, as transport costs have a large impact on delivered price per ton.
The gravel surface layer should be 2–4 inches deep after compaction for best performance. For loose surface gravels like #57 stone or 3/4-inch crushed, 3 inches of depth after light compaction is the standard minimum. For crusher run used as the surface layer, 3–4 inches firmly compacted is recommended to develop the binding hard-pack characteristic. Under 2 inches of surface depth will result in bare patches appearing through to the base layer within one driving season. When top-dressing an existing driveway, apply 3–4 inches of new material and compact lightly to integrate it with the existing surface beneath. The sub-base depth is equally important — see the depth guide table above for full specifications.
For driveways that wash out in heavy rain, the solution is twofold: correct material and correct grading. Use #57 angular crushed stone or 3/4-inch angular crushed stone as the surface material — the angular shape interlocks and resists water movement far better than rounded stone. Use compacted crusher run as the base course to create a firm foundation that doesn’t erode. Never use pea gravel or smooth river rock — rounded stones have no interlock and wash away immediately in moving water. Equally critical is the driveway crown: a 2% slope from the centreline to each edge ensures rainfall flows off the sides of the driveway rather than channelling along its length. Flat driveways with rounded stone wash out faster than any other combination.
Yes — the base layer for a gravel driveway is not optional if you want a long-lasting result. The sub-base is the structural foundation that prevents the surface layers from sinking, rutting, and shifting under vehicle loads. Without a proper 6-inch compacted sub-base of angular stone, even the best surface gravel will compress into the native soil, create potholes, and require constant re-grading within 1–3 years. The stone for driveway base should always be angular (class 2 base rock or large crusher run), never rounded. The base layer investment is modest relative to total project cost but has a disproportionately large impact on how long the driveway lasts and how it performs under daily use.
Crusher run — also known as road base, crush-and-run, processed gravel, or driveway mix — is a blended crushed stone aggregate containing both coarse angular pieces (up to 3/4 inch) and fine stone dust. The mix of sizes is what makes it exceptional for driveways: the fine particles fill the gaps between the larger angular pieces and bind together under compaction and moisture, creating a dense, cohesive surface that behaves almost like a low-grade paved surface. It weighs approximately 112 pounds per cubic foot (1.51 tons per cubic yard). Cost ranges from $20–$45 per ton. It is the most recommended driveway gravel material by landscape contractors for most residential applications because it delivers the best stability-per-dollar of any commonly available driveway aggregate.
