Petromat Overlay State Lic # 799983
Cracked pavement allows surface water to permeate to the sub-grade soils, which in turn saturate, weaken the sub-grade which allows further damage of the pavement surface.
A typical remedy to this situation would be to repave the damaged areas with an Asphalt overlay. This process can extend the life of the total area at a much lower cost that removal and replacement of the entire pavement surface.
However, the new pavement can be subject to the same type of damage as the surface just covered and nothing was done to stop the sub-grade soil moisture from permeating the new surface from below.
Petromat is a special polypropylene material configured in such a way as to significantly reduce the mechanisms that cause the surface pavement to deteriorate. In fact it increases pavement life by 50% or more. Actual field testing data supports increases in overlay life up 150%.
State DOT's reported that the performance of paving fabric in the pavement systems is equal to the application of an additional 1.5 inches of Asphalt.
Some of the benefits of using this process are:

Some of the benefits of using this process are:
- Provides a waterproof barrier for sub-grade protection
- Improves the fatigue resistance of the new overlay by providing a stress relieving interface
- Retards the propagation of an existing crack through the new overlay (reflective cracking)
- Extends useful life of the overlay by as much as 150%
So before to slurry coat that cracked old pavement one more time, give us a call so we can discuss this process in more detail with you.
