Bending Characteristics for Asphalt Concrete Beams with Bond Interface

摘要: The shear characteristics of bond interface in asphalt concrete (AC) has been widely studied along with the effects bonding conditions on pavement mechanical responses. However, no study focused bending for between layers. This paper investigates AC beams using a three-point bonded beam test. For comparison, test integrated without is also conducted. Bending strain and fatigue are performed specimen medium setting modified emulsion tack coat. resistance life measured. influence coat application rate, temperature, loading level layer investigated. results show that an optimum rate desired. At optimal integrity properties layers enhanced. it found different methods testing temperatures can result rate. Finally, regression model hot mix (HMA) developed based three factors including level.
