Hot Mix Asphalt Open Graded Resurfacing Layer

An asphalt crack relief layer or open graded resurfacing layer was used to mitigate reflective cracking from appearing on the surface of new overlays. This layer separates the existing deteriorated PCC pavement from the new overlay. The open graded nature of this layer will also be advantageous for draining excess water out of the pavement structure. Cores will be taken and material tests performed towards the end of the overlays life cycle to determine the effectiveness of the open graded layer
