摘　　要：采用马歇尔试验、车辙试验等方法研究了SEAM沥青、特立尼达湖沥青、法国PR PLAST.S抗车辙剂三种材料分别改性的沥青混合料的高温稳定性.研究结果表明3种改性混合料的马歇尔稳定度和车辙动稳定度较普通沥青混合料均有较大程度的提高,车辙最大变形量也明显减小,其中法国PR PLAST.S抗车辙剂对提高混合料的高温性能更为显著。因此建议在炎热地区高速公路建设中优先选用抗车辙剂。By use of the Marshall test and wheel tracking test the high-temperaturestability of the asphalt mixtures with the SEAM asphalt, the TLA asphalt and the France PR PLAST. S anti-rutting agent. Research results showed that the anti-high-temperature performance for 3 kinds of modified asphalt mixtures were a greatly obvious improvement than that of the conventional asphalt mixtures. Such as the marshall stability and dynamic stability of 3 kinds of modified asphalt mixtures raise evidently and their track deformation decrease significantly, of which France PR-rutting agent to raise the high-temperature performance on asphalt mixture was more significant. Therefore it is proposed to use first anti-rutting agent in the highway construction in hot areas.
