description abstract | Compared with flat slope sections of asphalt pavement, the loading time of low-speed vehicle load to uphill sections with long and large longitudinal slope is much longer, under the comprehensive combination of heavy load and high temperature. Developing and forming speed of rutting on uphill sections with long and large longitudinal slope is faster. Rutting factor and dynamic modulus of asphalt and asphalt mixture under different loading time will be calculated and analyzed in this paper. The results show that rutting factor and dynamic modulus were substantially reduced. Using the new rutting test equipments with the changing wheel speed and load to simulate the influences of overload and temperature (loading time) on asphalt mixture, the results show that dynamic stability is rapidly declined with the decrease of wheel speed. The loading time has vital influence on the high temperature stability of asphalt mixture. Increasing load time is equivalent to raising the experimental temperature, and using the temperature conditions in specification to verify the high temperature stability of asphalt mixture for uphill sections with long and large longitudinal slope is unreasonable. | |
