Petromat OverlayPetromat is a pavement reinforcing fabric specifically designed for the paving industry. Its primary function is to strengthen and reinforce the base course of asphalt upon which the new asphalt will be placed. An additional benefit is that it helps to mitigate mirror or reflective cracking (cracks in the existing asphalt) from coming up through to the new asphalt. The process involves laying a binder coat of hot oil which enables layers of asphalt to stick to one another, then laying the Petromat Fabric, and finally, overlaying these with a layer of asphalt, typically 1-1/4" and 2" thick. One important factor in determining whether or not to use this process is to keep in mind that overlaying raises the elevation of the existing parking lot. This is not always a desirable result. If it should be evident that raising the elevation of the parking lot is not an option, the next possibility would be to grind the existing parking lot down 1-1/2" to 2" and placing a new asphalt course over the newly ground parking lot.
