Can You Pour Asphalt Over an Existing Concrete Driveway?

When you want to update an old concrete driveway with high-quality asphalt, there are some things to keep in mind.

At Tucker Paving, we often hear from people interested in repaving a concrete driveway at their home or business with asphalt. We strongly recommend asphalt for any driveway as the benefits far outweigh any drawbacks. Asphalt is the best choice for driveways because it can be installed quickly and is more resistant to weather damage than concrete is. However, if you already have a concrete driveway that you want to replace with asphalt, there are some important points to consider.

Switching From Concrete to Asphalt
The first thing to consider is whether you need to remove the concrete driveway or if you can simply pave over it. The determining factor here is what lies underneath. Concrete itself is very stable and strong, so no matter what it is poured over, the slab is going to be solid when it hardens. Therefore, concrete is often used as a bridge over unstable ground. Asphalt requires a well-prepared, stable subbase, otherwise the resulting pavement will be subject to instability and cracking.

Asphalt driveways that are paved over an appropriately compacted subbase will always be superior to asphalt that is laid over an unstable base or concrete that is prone to shifting and expansion. Concrete is poured with expansion joints that allow room for the pavement to expand in hot weather. These joints can turn into cracks in the asphalt, which will necessitate expensive and time-consuming repairs. Your best bet is going to be to tear up the old concrete before pouring the asphalt.
