Samenvatting
In 1987, the County of San Diego, California, Department of Public Works developed test sections on Yaqui Pass Road to evaluate the performance of several surface treatments. The goal was to find a treatment to retard reflective surface cracks under desert conditions. While all of the treatments used sealed the road surface well, only chip seal over fabric eliminated reflective surface cracks. Moreover, a 30-year life-cycle cost analysis showed that the annual cost was one-half that of chip sealing with crack sealing. This article provides further details on the fabric properties, fabric placement, chip seal placement and product performance.
