  • Tar and chip driveways are low-cost but only last 7 to 10 years.

  • Tar and chip stones come in a variety of colors.

  • Chip sealing differs from asphalt seal coating and is not a repair method.

Install type Cost per square foot
Single chip seal $2 – $3
Double chip seal $3 – $5

Single chip seal

Single chip seal driveways cost $2 to $3 per square foot and include a layer of 3/8" to 3/4" aggregate laid over a liquid asphalt emulsion and compacted. Single chip seal:

  • Improves traction

  • Protects the pavement from moisture

  • Works best for resurfacing driveways with minimal cracks or damage

Double chip seal

Double chip seal driveways cost $3 to $5 per square foot and feature one layer of asphalt emulsion with 3/8" to 3/4" aggregate followed by a second layer with smaller aggregate. Double chip seal is more durable and protective and is used for new driveway installations and resurfacing.

High-performance / cape seal

High-performance chip seal, also called cape seal, features a modified asphalt emulsion and single-sized, cubical-shaped aggregate for maximum traction and skid-resistance.

High-performance chip seal is used for public roads and is typically followed by a slurry seal to increase durability.

Macadam driveway cost factors

Site prep and grading

Installing a chip seal driveway may involve the following site prep costs:

  • Yard grading and leveling costs $3 to $8 per square foot and ensures the driveway's foundation is structurally stable.

  • Excavation costs $1 to $5 per square foot to remove plants, soil, and small trees from the site.

  • Driveway repairs cost $300 to $2,500 on average. When installing chip seal on top of an existing driveway, the installer must repair any cracks, potholes, or sagging first.

Stone type and color

The choice of stone color and type affect the installation price. Stone options depend on the location and the types of stone available in the region. Using locally sourced stone is cheaper than importing stone from suppliers in other states.

Weather and climate

Tar and chip driveways must be installed when the weather is dry and air temperatures are warmer than 50° F. Paving a driveway in the summer typically costs less and results in a stronger, more durable surface.

Location and accessibility

Chip seal driveway prices depend on the home's location, distance from the installer and the nearest tar plants, and how far the stone must travel from the supplier to the job site.

The terrain and accessibility of the job site also affect the project price. Installation costs increase for driveways with landscape obstructions that make it challenging to maneuver heavy equipment.

Slope and pitch for oil and stone driveways

Driveways should be sloped away from the home for proper drainage. The minimum recommended grade for a driveway is 2%, and the maximum is 15% to 25%. Driveways with steep slopes cost more to install and require transition zones with reduced slopes at the garage and street.

Driveway permit fees & regulations

Driveway building permits cost $50 to $200, depending on location. Most cities require a permit for new driveway installations but may waive the fee if there's already a paved apron connecting the property to a public street.

Land survey for new driveways

land survey costs $200 to $1,200 on average, depending on the location and the planned driveway size. A professional land surveyor ensures the new driveway doesn't encroach on a neighbor's property.

Chip seal vs. asphalt vs. gravel driveway cost

new driveway costs $2,500 to $6,500 on average. Asphalt driveway paving costs $3 to $7 per square foot, a gravel driveway costs $1 to $3 per square foot, and a concrete driveway costs $4 to $8 per square foot.

Installing chip and seal over other driveway types

Chip seal can be installed over concrete, gravel, or unsealed asphalt driveways. The existing subbase must be in good shape, structurally sound, and cracks and holes in the surface require repairing before laying chip seal on top.

  • Good candidates for chip seal: surfaces with a stable foundation and only minor cracks and oxidation.

  • Poor candidates for chip seal: surfaces with cracks wider than 1/4", structural issues, or rutted pavement.

Chip and seal over concrete

Make sure the installer takes these steps before laying chip and seal over a concrete driveway:

  • Confirm the subbase beneath the concrete is stable and the surface hasn't shifted at the expansion joints.

  • Fill and seal any cracks. If the concrete cracks, the new asphalt laid on top will crack too.

  • Use a bonding agent to adhere the asphalt emulsion to the concrete below.

Tar and chip over asphalt driveway

Laying tar and chip over an asphalt driveway protects the surface from moisture and extends the driveway's lifespan. However, chip sealing over asphalt is only possible if the driveway's foundation is structurally sound, there is only minimal surface damage, and the asphalt has never been sealed.

Chip seal over gravel

Chip seal over gravel creates a smoother surface that improves drainage and reduces dust and loose aggregate. Before laying a new chip seal surface over an existing gravel driveway, fill any potholes and ensure the gravel base is level.

Chip seal over dirt

When installing chip seal over a dirt road or driveway, the installer first lays a gravel base for structural support then covers it in layers of liquid asphalt and stone chips.

Chip and seal driveway pros and cons

Chip and seal driveway pros and cons
Pros Cons
  • Cheaper than asphalt or concrete
  • Better traction when wet or snow-covered
  • Anti-glare surface in wet weather
  • Variety of colors and stone types available
  • Cooler surface temperature
  • Low maintenance with no sealing required
  • Self-healing: small cracks seal themselves in warm weather
  • Shorter lifespan than asphalt or concrete
  • Susceptible to weather damage
  • Snow removal is difficult. Easily damaged by snowplows if the blade is not raised to 1" before plowing
  • Surface is too rough for biking, basketball, and roller-skating
  • Difficult to find experienced installers

What is chip seal paving?

Chip and seal paving involves applying hot liquid asphalt sprayed 1/4" to 3/8" thick, followed by a layer of stone aggregate and pressed via a blacktop roller. Chip seal gets its name from the small chips of crushed stone that form the driveway's surface.

How long does a tar and chip driveway last?

Tar and chip driveways last 7 to 10 years on average. Adding a double layer of chip seal increases the lifespan to 12 to 15 years. In comparison, asphalt driveways last 15 to 30 years, and concrete driveways last 30 to 40 years.

What colors do chip seal driveways come in?

Tar and chip driveways come in a variety of individual stone colors and multi-color blends:

  • Gray, slate, and black

  • Brown, tan, and gold

  • Red, burgundy, and pink

  • White and marble

  • Bluestone, indigo, and oyster blue

  • Green and seafoam

Blue chip driveway

Blue chip driveways feature stones ranging in color from indigo to shades of light blue and gray. Bluestone is commonly used in stone pavers but also comes in gravel and aggregate for chip seal driveways.

Red chips for driveway

Red chips for driveways come in shades ranging from dark brick red to burgundy and pink.

What is the difference between asphalt and chip and seal?

Asphalt paving and chip sealing use the same ingredients but different construction methods. The chip sealing process involves spraying heated liquid asphalt followed by a layer of small stone aggregate. The stone is compacted with a heavy roller then covered in another layer of loose stone chips.

Can you seal coat a gravel driveway?

You cannot seal coat a gravel driveway, but you can chip seal one. Seal coating and chip seal refer to two different processes:

  • Seal coating refers to spraying a protective coat on an asphalt surface.

  • Chip seal features a layer of liquid asphalt emulsion with a layer of crushed stones spread on top and compacted. Chip seal smooths a gravel driveway and reduces dust and loose aggregate.

Where do you buy tar?

Local asphalt suppliers sell contractor-grade liquid asphalt emulsion for paving a tar and chip driveway. Home Depot, Lowes, and other hardware stores sell tar for roofing and cold mix asphalt for patching driveways.

How much does an oil and stone driveway cost?

Oil and stone driveways cost $2 to $5 per square foot, depending on site conditions, stone type and color, and labor costs. Oil and stone is also known as chip seal, macadam, or tar and chip.

DIY chip and seal driveway

Installing a chip seal driveway is not a DIY project. Tar and chip paving requires heavy machinery, special equipment to heat and spray liquid asphalt, and a crew working together to spread and compact the stones quickly. For the best results, hire a professional who specializes in chip sealing.

Hiring tar and chip driveway contractors

Tar and chip driveway installation requires special equipment and techniques. Not all asphalt companies have proper experience. Before hiring an installer and signing a contract, be sure to:

  • Confirm the company has experience installing tar and chip driveways (also known as chip seal, macadam, or oil and stone).

  • Get at least three estimates to compare. Let professionals know you’re getting bids from multiple companies so they offer you their best competitive price.

  • Read reviews and check out their previous work on HomeGuide and Google.

  • Select companies that are insured, bonded, and have been in business for 5+ years.

  • Avoid selecting the lowest quote as quality may suffer.

  • Ask for a written contract, warranty, and detailed estimate with a full breakdown of all costs involved.

  • Avoid making large payments upfront. Come up with a payment schedule for work completed.
