What Drives the Cost of a Driveway Replacement in Maryland

Why the estimate starts at the property

The Colorado Asphalt Pavement Association's driveway best-practices brief, published by the Asphalt Institute, says that before giving advice on a driveway it is wise to look at the actual site conditions: the subgrade soil type, drainage, the presence of utilities and the type of loads the driveway will carry. Those are the same things that move a price, which is why South State Paving gives free estimates at the property rather than over the phone.

What is under the surface

The same brief says the subgrade should be graded smooth, made free of organic material, and have weak spots undercut and replaced with suitable material. How much of that a driveway needs is not visible from the street, and it is one of the main reasons two driveways of the same size can price differently.

Thickness

The Colorado Asphalt Pavement Association says a base course of 6 to 8 inches of crushed aggregate is usually adequate, and that the ordinary residential driveway should have a 2-inch asphalt bottom course covered by a 1.5-inch surface course. The National Asphalt Pavement Association says the pavement thickness should be written into the bid, which is the easiest way to compare two estimates on equal terms.

Drainage

The National Asphalt Pavement Association calls standing water the leading cause of driveway failure and says the bid should spell out drainage responsibilities. The Colorado Asphalt Pavement Association says drainage, crown and slopes need to be addressed in the design. Regrading or adding drainage adds work, and it shows up in the estimate.

Removing the old driveway

The National Asphalt Pavement Association says asphalt is 100% recyclable and that a removed driveway is typically taken back to a plant to be processed into new pavement. Tear-out and hauling are part of a replacement estimate.

Resurfacing instead of replacing

The Colorado Asphalt Pavement Association says an existing driveway can be overlaid with hot-mix asphalt to improve and strengthen it, provided weak spots, holes and large cracks are cut out and patched first, and that an overlay of 1.5 to 2 inches is usually sufficient. Whether that is an option depends on what is found at the estimate.

Permits and the Critical Area

The Maryland State Highway Administration says everyone accessing a state highway from a residential property must obtain a residential entrance permit, and that the SHA approves the entrance's location, design, drainage and paving cross section. Near the water, the Maryland Department of Natural Resources says all land within 1,000 feet of tidal waters and tidal wetlands is in the Chesapeake Bay Critical Area, where construction is subject to limits on lot coverage. County and town roads have their own permit offices.

Comparing two estimates

The Colorado Asphalt Pavement Association advises getting more than one written quote, checking references and looking at the contractor's older work, and making sure the contract spells out dates, dimensions, material types and thicknesses, drainage, utilities, permits and damage to adjacent areas. The Maryland Home Improvement Commission says to check that the contractor is licensed: home improvement work without a license is a criminal offense, and homeowners who use an unlicensed contractor have no Guaranty Fund protection. South State Paving's license is MHIC #05-169105.

What the soil survey says, town by town
