Concrete Stability is Important for Paving Concrete is not usually a compacted surface because it hardens no matter what it is poured over. Trust Trained Paving Professionals Wolf Paving has engineers and paving professionals on staff with the knowledge and expertise to do the proper preparation needed to ensure your asphalt over concrete surface is built with durability.

This means the team at Wolf Paving will ensure your new surface is installed properly with these steps: Ensuring the base has a uniform thickness. But whitetopping can only be done on asphalt with moderate deterioration. In more severe cases, the asphalt will need to be entirely uprooted and the area will need to be repaved. You first need to look at the degree of deterioration to determine whether whitetopping can be done. If the deterioration of the asphalt surface is minor, and no greater than 2 inches deep, then whitetopping can be used.

If the asphalt has more substantial deterioration, you will need to remove all of the existing asphalt and repave. Generally speaking, we recommend removing the existing concrete first, for two big reasons.

The big problem with laying asphalt driveways over concrete has to do with the initial preparation of the site.

With concrete, if you're concerned about strength and stability, the solution is to simply lay a thicker slab. Because of this, contractors laying concrete rarely worry about preparing the base. The ground underneath a concrete driveway may be prone to shifting or sinking, and there's really no way of knowing what's down there until it's dug up. If something is wrong with either of these layers, it will show through the asphalt. Unfortunately, when asphalt driveways are poured over concrete resting on an unstable base, the resulting asphalt pour is prone to instability.

Expansion joints in the concrete will quickly turn into cracks in the asphalt, which will require costly ongoing repair jobs.

In extreme cases, shifts in the ground could crack the entire surface, just as a house's foundation may crack if improperly laid. So yes, pouring asphalt over concrete may look good at first, but there are bound to be troubles over time. It just doesn't make fiscal sense to do it, as that driveway will need a lot more work in the near future.
