9 Different Types of Driveway Materials – Cost, Durability, and Lifespan

Driveway materials form the surface that carries daily traffic and weather, with cost, durability, maintenance and drainage influencing the choice. This comparison covers driveways made of asphalt, concrete, gravel, tar-and-chip, brick or concrete pavers, stone cobblestones, resin-bound gravel, grass and permeable grid pavers, or pervious concrete, with base design depending on the system. There are nine options in our comparison, from basic gravel and asphalt to patterned pavers and surfaces that admit rainwater. EPA groups permeable pavement into porous asphalt, pervious concrete and permeable interlocking concrete pavement. To choose the best driveway material for a site, we would usually compare the pros and cons by build, cost, published service life, environmental impact and upkeep before asking which material is most popular.

1. Asphalt

01 asphalt paver

Asphalt is a blacktop of aggregate, the stone and sand, held in an asphalt binder, the bitumen, laid over a compacted crushed aggregate base. The Colorado Asphalt Pavement Association’s 2005 residential design uses a 2 in. bottom course under a 1.5 in. surface course, about 51 and 38 mm, on 6 to 8 in. of crushed aggregate, about 150 to 200 mm. Published service lives differ, from up to 20 years of trouble-free service for the Colorado association to 10 to 30 years in Fine Homebuilding’s 2008 comparison and 20 to 30 years in This Old House’s June 2026 article. Asphalt stays flexible after it is fully dry, which makes it less prone to cracking from temperature changes. When the surface wears, an overlay of 1.5 to 2 in. of surface mix, about 38 to 51 mm, renews it once weak spots, holes and large cracks are cut out and patched, which strengthens the driveway and extends its service life without a full teardown.

Our pick for: Long-lasting, budget-friendly driveways where appearance is less critical

Asphalt needs upkeep to reach its full lifespan, and the two asphalt bodies time it differently. The Colorado association’s 2005 advice is to wait until the driveway is at least several months old and then apply a sealer every two to five years, while the Asphalt Institute expects a well-built driveway to need no sealing for about 2 to 5 years, depending on climate and the quality of the original work, and to be sealed as soon as it shows the distresses sealing treats. Beyond ordinary asphalt, installers also offer imprinted decorative asphalt that gives the look of brick, stone or slate.

TIP

To extend the life of an asphalt driveway, seal it as soon as the surface turns dry and brittle, shows small cracks or begins to ravel, the loss of surface aggregate, with a light application of slow-setting asphalt emulsion diluted with water, the method the Asphalt Institute recommends. It does not recommend commercial sealers containing coal-tar compounds.

2. Concrete

Concrete forms a cast driveway slab on a compacted base. County Materials’ concrete-driveway guide recommends a slab of at least 4 in., about 100 mm, and 5 in. or more where garbage trucks or other heavy vehicles travel, about 127 mm, over 6 to 12 in. of compacted gravel or crushed stone, about 150 to 300 mm, with a minimum slope of 1/4 in. per foot, about 2 percent. For driveways exposed to deicers and freeze-thaw cycles, the very severe exposure class of ACI CODE-332-20, as summarized by the Tennessee Concrete Association, specifies 4,500 psi at 28 days, about 31 MPa, a maximum w/cm of 0.45, air entrainment of 6% plus or minus 1.5% for 3/4- or 1-inch nominal maximum aggregate, and a minimum thickness of 3 1/2 in., about 89 mm, and local adoption decides which edition of the code governs. Published service lives range from 30 to 50 years in Fine Homebuilding’s 2008 comparison to 50 years with minimal maintenance in This Old House’s June 2026 article.

02 concrete pavers
Our pick for: Long-term durability and low upkeep

A broom finish works well on exterior concrete because it is slip resistant, and the types of concrete finishes cover the decorative options. Concrete can crack, particularly during freeze-thaw cycles. Most random cracking traces to design and construction faults, among them missing isolation and control joints, poor subgrade preparation, very wet concrete or water added on the job, poor finishing and too little curing, and concrete shrinks slightly as it dries. County Materials estimates typical sealer lives of 2 to 3 years for membrane-forming sealers and 8 to 10 years for penetrating sealers. Concrete Sealers USA instead gives its TS200, TS201 and TS202 topical products up to 1 to 3 years and its water-repellent penetrating sealers up to 5 to 7 years or more, depending on exposure and wear; both undated sources were read October 22, 2026.

TIP

Keep salt and de-icers off a new concrete driveway for its first winter, consider a penetrating sealer once it has cured, and after that limit salt and de-icer use and remove the excess after use. For traction during the first year, use clean sand.

3. Gravel

03 gravel pavers

Gravel driveways use a surface layer of gravel or shingle over a sub-base. Readily available materials keep this form of construction cheap and straightforward to build and maintain. For a permeable gravel driveway, the City of Santa Barbara calls for at least 6 to 8 in. of compacted, washed, open-graded crushed stone, about 150 to 200 mm, with a minimum rock size of 3/4 in., about 19 mm, no binders or top layers and no filter fabric under the gravel, so rain soaks through.

Our pick for: Budget-friendly rural driveways

A gravel driveway’s life is a matter of upkeep. One published comparison gives gravel 90-plus years, and the upkeep is regrading every year or so and replenishing the gravel. Gravel will scatter or form waves, is not suitable on steeply sloping drives and is not suitable for wheelchairs. Weed control differs between the two governments’ designs: GOV.UK advises a geotextile over the soil to stop the sub-base sinking and help prevent weeds, and Santa Barbara’s permeable design puts no filter fabric under the gravel.

Gravel comes in different shapes and colors for a more decorative surface, and because loose stones travel, GOV.UK suggests a strip of block paving or asphalt at the entrance to limit the loss and spread of gravel, while Santa Barbara may require concrete, asphalt or pavers from the property line inward to keep gravel out of the public right-of-way.

We find gravel’s rustic, informal appearance well suited to rural or farmhouse-style properties. Aggregate geology varies by region, with limestone, granite and river deposits among the sources. Traffic on gravel can generate dust in dry weather. Gravel can spread, so we would define the edge to give the drive a cleaner outline.

4. Tar-and-Chip – Chip Seal

04 tar and chip – chip seal

Tar-and-chip, also sold as chip seal and called macadam in Fine Homebuilding’s comparison, is a middle ground between a full asphalt driveway and a loose gravel surface, an asphalt binder sprayed on a prepared surface and followed immediately by aggregate chips, leaving a firm, rough, textured surface. In that comparison, macadam is hot, liquid asphalt sprayed over a solid gravel base and covered with colored stone, and tar-and-chip the same method applied to an existing asphalt or concrete driveway. This driveway material gives an understated look, with the colored stone chosen to complement the home.

Our pick for: Rustic-look paved driveways with low maintenance

Published lives for tar-and-chip are short, 6 to 10 years for macadam and tar-and-chip against 10 to 30 years for asphalt in the same published comparison. When the surface wears, a new chip seal over it renews the driveway. Tar-and-chip has an intentionally rustic appearance, and a buyer after a very polished or uniform look may not want the slight variability and texture of a chip seal driveway.

TIP

The surface beneath decides how long a chip seal lasts. Expected service is six to eight additional years on pavement in good condition and three to four on poor pavement, so sound pavement under the chips is the longer-lived base.

5. Brick and Concrete Pavers

05 brick and concrete pavers

Pavers form patterned driveways and walkways from interlocking bricks, blocks or stones, including classic clay brick, concrete in a wide variety of shapes and colors, and natural stone cut to regular sizes, laid in patterns such as herringbone, parquet and running bond. A paver driveway is segmented into many small units, whose joints help reduce the cracking typical of conventional asphalt and concrete, and the same pavers can be removed and reinstated for repairs. CMHA, the Concrete Masonry and Hardscapes Association, recommends pavers 2 3/8 in. thick, 60 mm, for residential driveways and 3 1/8 in., 80 mm, for pavements subject to vehicular traffic, but its documents differ at the exact 4:1 length-to-thickness boundary. PAV-TEC-010 excludes ratios of 4:1 or greater from vehicular use, while PAV-TEC-009 permits a maximum of 4:1 for residential driveways; both were checked October 22, 2026.

Our pick for: High-end look with design flexibility and easy repairs

One published comparison gives 50 years for concrete pavers and 30 for brick pavers. In cold climates the base carries the risk, and base thickness may need to be greater for site conditions, freezing temperatures and traffic. Concrete pavers can have greater resistance to deicing salts than conventional paving materials because of high cement content, strength, density and low absorption. ASTM C936, in CMHA’s 2022 summary, sets a minimum average compressive strength of 8,000 psi, 55 MPa, and average absorption no greater than 5% for pavers made in the US, with freeze-thaw durability tested to ASTM C1645, whose active edition is ASTM C1645-22aε1, in a 3% saline solution where pavers will see deicers. ASTM’s active edition of the specification is ASTM C936/C936M-26.

Pavers go down on a 1 in. layer of bedding sand, about 25 mm, over the compacted base, with sand swept into the joints and the units compacted again, and where a section settles from a local deformation in the base, the pavers over it are lifted, the base is re-leveled and the same pavers put back. Rain soaks through the joints of permeable interlocking concrete pavement, PICP, one of the three permeable pavement types EPA recognizes. Edge restraints keep interlocking concrete pavers from spreading sideways under vehicle loads.

For a DIY paver driveway, we would price professional help for the base, grading and heavy cutting before committing to the work. We would compare paver quotations for the same excavation, drainage and base preparation, as well as the chosen surface units. CMHA recommends maintaining joint sand in conventional paving and lifting and reinstalling individual pavers for repairs. Permeable systems need their specified joint material. Polymeric sand can reduce weeds, but the University of California does not treat it as a complete weed-control solution. For permeable drives, brush away accumulated dirt and clear leaves before they clog the surface. Remove emerging weeds by hand.

6. Stone Cobblestones

06 cobblestone pavers 2

Cobblestone driveways use natural stone blocks and setts, including granite products sold for driveway use. Westminster distinguishes square-edged setts from rounded cobbles. Edinburgh’s 2017 guidance describes historic streets retaining original stone flags, setts or horonised surfacing. Stone setts, covered by BS EN 1342:2012, the standard for setts of natural stone, withstand weathering well and can last for decades with very little maintenance. Edinburgh rates setts as extremely durable with a long life span, though difficult to remove and prone to deformation.

Our pick for: Classic aesthetic

Marshalls’ October 2017 article specifies cropped granite setts for driveways on a minimum 150 mm sub-base, about 6 in., compacted in two 75 mm layers, a 15 to 30 mm bed of 3 to 1 sand-cement mortar, and 8 to 15 mm joints filled with a 4 to 1 sand-cement mix. Its November 2022 rigid-sett guide instead gives a mortar bed of approximately 40 mm; confirm the current specification for the chosen system. Laying each stone by hand over that solid base is time-consuming work, with joints often filled with sand or mortar.

Stone setts are costly and, except for flat-topped setts, produce an uneven surface. Natural stone paving combines high material costs with a need for skilled installation. We value cobblestone for its Old World character. Mortar-bedded and mortar-jointed setts form a rigid assembly. Permeability depends on the joints and the underlying base design; sand joints alone do not establish drainage performance. Maintenance includes weed management and replenishing joint material where the selected paving system requires it.

7. Resin-Bound Gravel

07 resin bound gravel

Resin-bound driveways combine the natural look of gravel with the solidity of pavement, small decorative stones premixed with resin and troweled over a prepared base. Resin-bound surfacing can form part of a SuDS-compliant system when its base, sub-base and drainage are designed for that purpose, while resin-bonded surfacing, aggregate scattered onto a complete layer of resin, is not porous because water cannot pass through. RonaDeck’s current specification, checked October 22, 2026, gives a minimum driveway layer of 18 mm for kiln-dried aggregates no larger than 6 mm. Its 2014 issue 37 specification instead gave a 15 mm layer over 60 mm of open-graded asphalt and 200 mm of Type 3 sub-base. Water passes through the open matrix into a suitably designed base. RonaDeck describes its resin as UV stable in typical UK conditions.

Our pick for: Decorative, seamless surfaces on a permeable base

That permeability suits resin-bound surfaces to places where stormwater rules are strict. In performance, resin-bound gravel is hard wearing, and Addagrip gives Addaset Eco, a resin-bound surface for domestic driveways, a typical minimum life expectancy of 15 to 25 years, separate from its 25-year warranty. Maintenance follows the chosen system’s instructions. Addagrip’s STONEBOUND manual specifies regular suction cleaning and sweeping to maintain drainage. We find the stone colors, blends and subtle sheen more decorative than plain concrete or asphalt.

Ronacrete’s 2014 specification describes RonaDeck for pedestrian and light vehicle traffic on drives, car parks and some access roads. Its 18 mm car-park build-up is for cars and light delivery vehicles. Those are system-specific limits; the current driveway surface thickness is also 18 mm, with the aggregate condition described in the current specification. A resin-bound layer needs a solid base and skilled installation; repairs can leave visible patches.

8. Grass and Permeable Grid Pavers

08 grass and permeable grid pavers

Grass block pavers and permeable grid systems give a drivable surface that still looks like a lawn or garden, concrete blocks or plastic grids with open cells filled with soil and turf grass, and both plastic and concrete reinforcement systems let cars drive over grass without causing ruts, with the plastic systems also usable with gravel. Concrete grid pavements infiltrate water at lower rates than permeable interlocking concrete pavement.

Our pick for: Eco-friendly driveways with green space or hidden parking

Reinforced grass can help to reduce temperatures around the house, absorb pollution and dust and reduce noise. Aesthetically, a grass paver driveway has a soft, natural look of living vegetation that blends into the landscape and makes a large parking area much less intrusive than a broad expanse of bare pavement.

Base preparation depends on the system. TRUEGRID’s typical residential gravel installation uses a 6 in. base, about 150 mm, in a residential driveway, set 1/4 in., about 6 mm, or slightly lower than the surrounding grade, while EPA describes concrete grid pavement designs as generally lacking a crushed stone base, which limits water storage. Grass in the cells is a lawn that may need mowing and maintenance to look tidy. Plastic grids can also use gravel infill, though it may require sweeping, particularly on a sloping driveway.

EPA describes concrete grass grids as suited to intermittent traffic, such as overflow parking and emergency fire lanes. That vegetation limit is distinct from grid strength: TRUEGRID requires an engineered base and other design provisions for heavy loading. Reinforced grass is not suitable where vehicles are parked continuously for a long period of time, as the grass may die.

Plastic-grid lifespan claims differ. TRUEGRID specifies 60 years for ROOT beside a ten-year warranty, but gives 25 to 60-plus years in its general FAQ and 20 to 25 years in its grass-paver guidance, all checked October 22, 2026. Invisible Structures claims 60-plus years for Grasspave2 beside a lifetime warranty and installations since 1982. A wheel-track drive is another option, two paved tracks typically 300 to 600 mm wide each, about 12 to 24 in., with gravel or planting between.

9. Pervious Concrete

09 pervious concrete 2

Pervious concrete is a special type of concrete designed to let water flow through it, a near-zero-slump, open-graded material of portland cement, coarse aggregate, little or no fine aggregate, admixtures and water, with a void content of 15 to 35%, as ACI PRC-522-23, the American Concrete Institute’s pervious concrete report, defines it. Its drainage rate will generally fall between 2 and 18 gal/min/ft², 81 to 730 L/min/m², varying with aggregate size and mix density. Pervious concrete reduces stormwater runoff, improves stormwater quality, may recharge groundwater supplies and can reduce the impact of the urban heat island effect. Permeable pavements generally need less road salt, because rapid surface drainage reduces freezing puddles and black ice.

Our pick for: Environmentally sustainable driveways and stormwater control

Pervious concrete’s environmental benefits come with limits on traffic and load. Permeable pavements can generally replace traditional pavement in driveway, pedestrian walkway, sidewalk and bike path applications, but EPA’s 2021 guidance is inconsistent about loading. Its limitations section excludes high volumes and extreme loads, while its applications discussion notes that some permeable concrete handles heavier loads. Structural design must address the expected traffic. Typical compressive strengths are 400 to 4000 psi, 2.8 to 28 MPa. Installation differs from normal concrete, since pervious concrete should be poured within 1 hour of mixing unless admixtures extend handling time and should not be floated or troweled, which may close the surface pores. Its thickness is 4 to 8 in., about 100 to 200 mm, depending on expected traffic.

Maintenance of a pervious concrete driveway mainly involves keeping the pores clear. Clogging is the most prevalent maintenance concern for permeable pavements, and although it increases with age and use it generally does not lead to complete impermeability, and vacuum sweeping can increase permeability. Gunderson’s 2008 figures give properly constructed permeable concrete parking lots 20 to 40 years, against a typical 15 years for a conventional parking lot in a cold climate. Sand is not used on it for snow or ice, and plowed snow is not piled on it, since the melt can carry sediment that clogs it.

What Type of Driveway Lasts the Longest?

In Fine Homebuilding’s 2008 comparison, cobblestones and gravel have the highest listed service-life figures, both at 90-plus years, gravel only with regrading every year or so and replenishing, and Edinburgh’s 2017 guidance records historic streets retaining original stone paving. Concrete follows at 30 to 50 years and asphalt at 10 to 30 years in the same comparison, and tar-and-chip has the lowest figure in that comparison, at 6 to 10 years.

What Are the Parts of a Driveway?

The parts of a driveway are, from the bottom up, the subgrade or native soil, the sub-base or aggregate base, a bedding layer under pavers and setts, the surface itself, and at the street end the apron, the part of the driveway approach between the street and the sidewalk or property line.

The sub-base carries the load. Both permeable and impermeable driveways have a sub-base that makes the ground strong enough to carry cars without rutting, hardcore or MOT Type 1 for a conventional drive and open-graded stone such as 4/20 or Type 3 for a permeable one, with about 150 mm, about 6 in., of compacted sub-base over a geotextile in UK guidance, and a drive should slope away from the house towards the road wherever possible.

At the street, the City of Los Angeles defines the driveway approach as the area of a driveway in the public right-of-way between the street flow line and the property line, including the apron, side slopes and curb returns, and names the portion within the Y distance the Y slope.

Choosing the Right Driveway Material

Driveway material selection balances the site’s conditions, the available budget and the owner’s preferences. Loose gravel and wheel-track drives are cheap and simple to construct, and hard permeable paving can be more expensive than other options. Routine maintenance also affects the choice. Hard permeable surfaces require the least maintenance among the options compared in the 2009 GOV.UK permeable-driveway guidance. Stone setts need little maintenance, while gravel and grass grids ask for regrading, replenishing or mowing.

Traffic and vehicle weight determine the required structural design. County Materials advises that concrete 5 in. or more thick may be necessary for heavy vehicles. Paver thickness and the underlying base must suit the expected loads. Grass health can limit continuous use even where a plastic grid supports heavy vehicles; EPA’s differing permeable-concrete loading statements also require a design-specific decision.

For a seldom-used rural driveway, we would consider gravel or tar-and-chip. Our aesthetic preference is to complement the home’s style, for example rustic gravel or stone for a country cottage, sleek concrete or resin-bound aggregate for a modern home, classic brick pavers for a traditional house. A professional contractor or landscape architect can advise on what works in the local soil and climate.

Before making a final decision, check with local building and zoning authorities or homeowners’ associations, since some communities restrict driveway materials or require drainage features. In England since 1 October 2008, a house needs no planning permission for a new or replacement front-garden driveway of any size that uses permeable surfacing such as gravel, permeable concrete block paving or porous asphalt, or drains its rainwater to a lawn or border, and a traditional impermeable driveway over 5 m², about 54 sq ft, without that drainage needs it. These allowances apply to houses, not to flats or maisonettes, and not where a planning condition or Article 4 Direction restricts them.

What Drives the Cost of a Driveway?

The specified build suggests more about a driveway’s cost than the surface name alone. Base depth comes first, rising with site conditions, freezing temperatures and traffic, and slab thickness follows load, from a 4 in. minimum to 5 in. or more under heavy vehicles. Ease of installation moves it too, since porous asphalt should be provided and laid by a specialist company. A drive sloping towards the house needs a drainage channel, and in England a house’s impermeable front-garden surface over 5 m², about 54 sq ft, that does not drain to a lawn or border needs a planning application. Material choice moves the cost too. For the most cost-effective driveway, loose gravel is cheap, and permeable surfaces in general do not necessarily cost more or require a lot of maintenance.

  1. My property has a gravel driveway which I inherited. Problem is lots of weeds grow anually even though I spray with heavy duty weed killer each year. It is getting extremely difficult for me physically to constantly weed the driveway several times each year. Is is possible to have the loose gravel replaced with a resin bound gravel using the existing gravel? And what would be the cost per metre?
