With proper maintenance, asphalt milling driveways can last 30 years or more. Over time, you’ll need to regularly sealcoat your driveway. You should also have your driveway inspected every few years and make any repairs as soon as they are necessary; this will prolong the lifespan of your driveway.

An asphalt driveway costs between $3,150 and $7,400, depending on the size of the driveway and the depth of the asphalt. Expect to pay between $2 and $6 per square foot for materials and $5 to $7 per square foot for labor. Although installing asphalt yourself will save you on labor costs, it might ultimately cost you more when you make a mistake.

Even with regular maintenance, most driveways don’t last much longer than 30 years. Alligator cracking is a clear warning sign that your driveway’s foundation is failing, and cracks that are deep and wide can let water in, causing more damage. Standing water is another red flag. If your driveway doesn’t drain properly, it’s going to degrade slowly. Finally, if you’re seeing dips or uneven patches, that’s a sign the base layer or soil is shifting. If these issues pop up, it’s time to replace your driveway.

On average, asphalt dries within 24 to 72 hours, meaning it’s solid enough for light traffic—walking and careful driving. Full curing—when asphalt reaches peak strength—can take anywhere from three months to a year. During that time, heavy loads and sharp objects can leave marks. Weather, asphalt mix, and thickness all affect how quickly it dries and cures. If you want your asphalt to last, treat it gently until it’s fully cured. For the best results, check with a professional asphalt contractor for their advice.
