Avoiding Early Failure of Intersection Pavements
The primary mode of failure of the intersections studied was rutting with shoving in some cases. The leading materials related cause of pavement failure was asphalt content in excess of the designed value. Most of the mixtures studied contained relatively high percentages of uncrushed sand and low voids in the mineral aggregate. Modifications in materials specifications, laboratory test techniques design procedures, and construction methods are suggested to provide a margin of safety to minimize early failures. The potential for significant economic benefits appears promising when intersection approaches are designed and constructed to accommodate the special stresses to which they are subjected.
