Can you pour concrete over asphalt.
It is safe to pave asphalt over concrete.
2 go by what they tell you.

Homeowners can benefit from this whitetopping technique to reduce labor costs and time when replacing worn asphalt driveways.
An asphalt overlay is cheaper to install than replacing concrete and can provide a smooth ride over deteriorating concrete.
To save time and money many states and municipalities use a road repair technique known as whitetopping the process of pouring concrete over asphalt rather than removing the existing asphalt.
The truth about asphalt over concrete.
Asphalt requires a well prepared stable subbase otherwise the resulting pavement will be subject to instability and cracking.
Well the answer is yes.
It will however require a little more maintenance than a typical asphalt overlay.
Asphalt can be successfully installed over concrete but due to the characteristics of each material you may not be happy with the long term results as the asphalt will ultimately crack in the same manner that concrete does.
It is called an asphalt treated permeable leveling course.
Therefore concrete is often used as a bridge over unstable ground.
This is constructed by placing and compacting the base material and then placing about a 3 layer of permeable asphalt.
Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above.
You can put asphalt over concrete but professionals don t advise it.
The 1 thick concrete will not have any strength it will simply break up under any pressure.
There are situations where we commonly put concrete over asphalt when building roadway pavements.
In fact many miles of concrete roads are paved over with asphalt every year.
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.
