Abstract:
Recently, a new method to investigate chip seal performance has developed by a research team at Sharif University of Technology. This study investigates the effect of various additives such as CRM, SBR Latex, Hydrated Lime and Ordinary Portland Cement (OPC), on the curing time of chip seal by this method. In addition, the chip seal treatments were investigated in different climate conditions like Wet and Wet-Freeze zones. The overall performance of mixture specimens evaluated using creep loading test. In fact, the bonding properties between aggregates and surface of Hot Mix Asphalt measured. The test results were analyzed by using of the work and time parameters. These parameters were calculated from beginning of the test to the beginning of the tertiary creep regime. The results of this research indicated that the Hydrated Lime and OPC additives contribute to chip seal treatments significantly and Wet-Freeze agent has the most destructive effects on chip seal performance
