Pavement Overlay


Moisture, expansion and contraction due to temperature changes and traffic loads, all contribute to the vertical and horizontal movements of the pavement causing cracking, when new overlays are applied to such surfaces, the cracks soon resurface in the new overlay, known as reflecting cracking. 


ALYAF PU overlay fabrics offer a cost-effective and proven method of retarding the reflecting cracking. It also acts as a moisture barrier that prevents the ingress of moisture into the sub grade and increases the fatigue resistance of the pavement structure.
