Driveway Sealcoating questions, answered by experts

The cost of asphalt driveway repair is usually similar to the cost of average concrete driveway repairs, but maintaining asphalt tends to be less expensive on a per-instance basis. For example, resurfacing asphalt costs about $1 less per square foot, but it doesn’t last as long as concrete and will need more frequent repairs. An asphalt driveway lasts 20 to 25 years, but a well-maintained concrete driveway can last twice as long, so the maintenance costs and timeline even out.

Small cracks can be DIY patched, but professional services ensure durable, smooth surfaces and prevent further deterioration.

It depends on the type of sealer. Some sealers can dry in as little as 4 hours, but many can take up to 48 hours to fully cure. To play it safe, don’t drive on your driveway for two days after sealing.

Commercial lots should be sealed every 2-3 years to prevent cracks and weather damage.

Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.
