There’s no single best asphalt grade—it all comes down to where and how it’s used. Highways and heavy-traffic roads need something tough, like polymer-modified asphalt (PMA) or Stone Matrix Asphalt (SMA). Local roads and parking lots rely on the Performance Graded (PG) system, chosen based on climate. A PG 64-28 mix, for example, handles a broad temperature range while simpler, more cost-effective mixes are typically enough for residential driveways. The best grade of asphalt depends on traffic, weather, and your budget, which is why a professional’s input is always a smart move before making a decision.

Three inches is a great thickness for a residential asphalt driveway that sees minimal to moderate traffic from cars, SUVs, and pickup trucks. However, a thicker driveway can better withstand the weight of a heavier vehicle, such as a trailer or a recreational vehicle. If you drive a heavy vehicle on a thin driveway, you risk cracking and damaging it.

The cost to replace a driveway ranges from $8 to $15 per square foot, depending on factors that include material, size, and labor. If your driveway has deep cracks, potholes, or drainage issues (or if it’s simply past its prime), replacement might be the smarter investment over constant repairs. Resurfacing can be a cheaper alternative at $3 to $20 per square foot, but it won’t fix your driveway’s underlying problems.

To ensure you hire a reliable and experienced paving company, you should start by finding companies in your area that have at least five to ten years of experience working in your neighborhood. Next, rule out companies with poor reviews online or a series of complaints filed with the Better Business Bureau. Since driveways affect your curb appeal, you should also ask each company for references and pictures of recent work to make sure the work the company does is professional and high quality. Finally, check that the company is licensed and insured.
