Petromat Paving Fabric Overlays

petromat overlaysPetromat overlays extend the life of commercial asphalt pavements

The petromat system, first introduced in 1966, extends the life of new asphalt pavement overlays. The petromat system consists of a non-woven polypropylene fabric which is field saturated with an asphalt cement tack coat. When placed between pavement layers, the petromat system becomes an integral part of the roadway section, forming a barrier to water infiltration and absorbing stresses to reduce reflective and fatigue cracking of the new asphalt surface layer. Challenge Asphalt has had tremendous success using the economical petromat paving system, especially as it improves pavement performance and lifespan of new asphalt pavement overlays, while reducing maintenance and lifecycle costs.

Petromat overlays absorb stresses, improving resistance to pavement fatigue and cracking

Petromat paving fabric saturated with asphalt tack coat forms a substantial inter layer media within, where stresses can be absorbed. Stresses associated with movement along cracks and joints in existing ac pavements are absorbed within the paving fabric system, and therefore are not translated or reflected up into the new asphalt overlay.

The benefits of petromat overlays include:

  • Strengthening and reinforcing the base course of asphalt so it can better withstand traffic loads
  • Mitigation of mirror or reflective cracking
  • Life extension of new asphalt pavement overlays
  • Improved pavement performance
  • Reduced maintenance and lifecycle costs
  • Longer pavement life in new asphalt concrete pavements


The key to the performance of petromat paving fabric is proper installation. Challenge Asphalt’s state-of-the-art petromat paving equipment and skilled crew are available to provide the highest quality petromat installation possible.
