Road Science Illustrated: Identifying Top-Down Cracking

This pull-out guide illustrates a variety of causes for top-down cracking in pavement and how to repair them. The article describes: 1) reflective cracking, which is the most common form of asphalt distress; 2) bottom-up fatigue cracking, which starts in the lowest layer; and, 3) top-down cracking, which follows wheel paths. The most common reason for pavement cracking appears to be mix segregation, and the solution is to seal cracks as soon as possible. The guide also explains how to prepare cracks for sealing as well as how to fill the crack. In addition, the guide includes two accompanying articles on top-down cracking which further discuss potential causes of top-down cracking.
