| 摘 要： | 为研究掺加抗车辙剂沥青混合料的高温性能,选用车辙试验和单轴静载蠕变试验,通过动稳定度(DS)、综合稳定系数(CSI)、高温劲度模量和Burgers模型对掺入国产A、国外A、国外B抗车辙剂的沥青混合料进行高温性能评价.车辙试验结果表明,掺加抗车辙剂后的沥青混合料动稳定度大幅提升,但动稳定度和车辙深度的背离导致其无法确定,...

| Abstract: | Based on the rutting test and uniaxial static creep test and by using the dynamic stability(DS),complex stability index(CSI),high-temperature stiffness modulus and Burgers model,the high-temperature performance of the asphalt mixed with three kinds of anti-rutting agent was evaluated.The results of the rutting test showed that,although the dynamic stability of the mixture was greatly improved,yet for the confliction between dynamic stability and rutting depth,it was difficult to discriminate the impacts of ... |
