摘要：

In order to reduce the use of petroleum asphalt in asphalt mixture, modified plant-asphalt was prepared with the plant-asphalt as the modifier. The test results of the conventional tests, DSR and BBR were analyzed, so that the best use level of plant-asphalt was determined, and the performance of modified plant-asphalt mixture and SBS modified asphalt mixture were compared. The results show that compared with the SBS modified asphalt, low temperature crack resistance and fatigue properties of modified plant-asphalt enhances, and high-temperature performance of modified plant-asphalt lowers; the modified plant-asphalt has an excellent performance when the content of plant-asphalt is 12% (by mass); the Marshall stability, dynamic stability, residual stability, low residual strength ratio and bending strain of modified plant-asphalt mixture are 0.88, 0.94, 1.08, 1.11, 1.15 times than those of ordinary SBS modified asphalt mixture, respectively. © 2017, Editorial Department of Journal of Building Materials.
