Development of Asphalt Cushioned Plastic and Plastic Reinforced Asphalt Membranes for Seepage Control
This project was concerned with laboratory equipment development, laboratory testing, construction equipment development and field investigation of the APAC (Asphalt-Plastic-Asphalt-Chip-Coated) water seepage barrier. The laboratory equipment that was designed and fabricated included hydrostatic testing vessels, slope stability apparatus, and tensile testing grips. Three testing methods were utilized and evaluated. The first test method evaluated the hydrostatic puncuture resistance of the asphalt-polyethylene combination. The second test investigated the slope stability of a protective APAC chip seal. A typical 3/8 in. (9.5mm) cover aggregate remained stable on constructed slopes of 3:1 and 4:1 and the 2:1 slope remained stable up to a surface temperature of 122F. The third test method evaluated adhesive materials and indicated that Presstite mastic was the best suited adhesive for sealing poleythylene overlaps. Subsequent field investigations resulted in equipment development that increased construction efficiency in the installation of the APAC membrane.
