Granular crack relief layer
WebThis crack relief layer was a 4.75-mm nominal size fine-graded mixture with 8 percent polymer-modified asphalt cement. It was compacted to 96 percent solid density to aid in retarding cracks and blocking water intrusion into the base. The mixture was designed with low air voids and the polymer was specifically suited for crack absorption. WebCracks will typically begin and end at the pavement edges and have a noticeable change in elevation across the crack and the road surface. ...
