Get matched with top asphalt driveway pros in Pleasant Hill, MO

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.

Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

A solid driveway starts with the right asphalt mix, and for most homes, dense-graded hot mix asphalt (HMA) is the most recommended. It’s both durable and flexible, making it a reliable choice for residential use. A properly compacted 2-3 inch layer on a well-prepared crushed stone base will hold up for years. In areas with harsh winters or scorching summers, a slightly modified mix can help prevent cracking and rutting. No matter the climate, quality installation is just as important as the material itself, so hiring an experienced contractor ensures a smooth, long-lasting driveway built to last.
