Long-Term Reflective Crack Monitoring of Asphalt Concrete Overlays
Abstract
A test section was constructed at Peterson AFB, Colorado, in October 1985 to study the ability of five different treatments to reduce reflective cracking in asphalt overlays. A summary of the cracking is given, and the performance of the treatments is evaluated. The saw cutting of the asphalt concrete overlay surface over the portland cement concrete joint is effective in reducing reflective cracking. The other four treatments are showing worse performance than the control sections. Variables introduced into the study have decreased the integrity of the results, and further survey and evaluations may not yield significant information. A test section was constructed at Maxwell AFB, Alabama, in July 1988 to study the ability of six different fabric interlayers to reduce reflective cracking in asphalt overlays on a nontrafficked pavement. The design and construction details of the test section are presented. Keywords: Rubber, Fabrics.
