Petromat Overlays

The greatest source of damaging water in road/pavement structural sections is precipitation infiltration through the pavement. Cracked pavement allows surface water to permeate to the sub-grade, or the the soil prepared to support the pavement system. Most pavements do not have adequate drainage systems to quickly remove infiltrated water. Petromat fabric, when saturated with asphalt cement tack coat, becomes a moisture barrier in the pavement, minimizing surface water infiltration.

Benefits of Petromat Overlay

• Creates Water Barrier: The use of petromat overlay provides a waterproof barrier for sub-grade protection.
• Improves Fatigue Resistance: Petromat overlay improves the fatigue resistance of the new overlay by providing a stress relieving interface.
• Retards Reflective Cracking: Reflective cracking occurs when cracks or joints in the underlying surface or base reflect through to the new asphalt surface. Petromat overly retards the propagation of an existing crack through the new overlay.
• Extends Asphalt Life Span: Using petromat overlay with regular maintenance can extend the useful life of your asphalt surface by as much as 150%.
