Test Study on High and Low Temperature Performance of High Grade Asphalt and Its Modified Product in Qinghai—Tibet Plateau Area |
| |
Abstract: | Based on the special conditions of landform, climate and environment in Qinghai-Tibet Plateau area, the paper intended to study the effects of temperature, frequency and other factors on the performance of different high-grade asphalt and the modified products. For high-grade asphalt, the high-temperature anti-rut factor and fatigue factor were determined by DSR test to evaluate the high-temperature stability and fatigue resistance and, with BBR test, the creep stiffness and creep rate were determined to evaluate the low-temperature cracking resistance performance. |
