Petromat® is a non woven polypropylene fabric. When used in combination with an asphalt tack coat, the Petromat® System forms an asphalt membrane interlayer within the pavement section. This layer acts as a barrier to surface water infiltration and limits weakening of the subgrade soil and base aggregate, and freeze-thaw damage, which could otherwise occur. The Petromat® membrane interlayer also absorbs stresses, improving resistance to pavement fatigue and reflective cracking. These combined Petromat® functions have been widely shown to extend the life of asphalt concrete overlays and chip seal surface treatments. Petromat® also promotes longer pavement life in new asphalt cement concrete pavements.
