Construction Report: U.S. Highway 36, Superpave Overlay of Sand Anti-Fracture Layer over AC/PCC Pavement. (Research Investigation RI99-042, RI97-045)
The sand anti-fracture (SAF) technology in implemented on U.S. 36 in DeKalb County, Missouri, during the summer of 2000. The SAF layer is a fine aggregate graded asphalt mixture using highly polymerized asphalt binder that gives the SAF layer the ability to withstand more strain compared to a conventional asphalt mix. The SAF layer was incorporated into MoDOT's rehabilitation strategy as a stress relieving membrane. The project includes two test sections that will be used to monitor the performance of the SAF layer. These test sections will be compared to each other to determine the SAF layers' effectiveness in reducing reflective cracking, decreasing future maintenance costs, and extending the life of an overlay. This interim report contains information regarding the construction of this project and initial SAF performance. Visual distress surveys and automated road analyzer (ARAM) data were conducted on the original pavement surface before construction to identify distressed pavement areas, and they also were conducted after construction to evaluate initial SAF performance. Visual distress surveys and ARAN data will be conduced annually until the performance of the SAF can be compared and evaluated to MoDOT's conventional methods, at which time a final report will summarize the findings.
