摘要
文章试验研究了不同PR/RA改性剂掺量的高模量沥青混凝土(HMAC)的抗车辙性能,分析了层位、层厚、模量、轴载、温度和荷载次数等因素对高模量沥青混凝土路面抗车辙性能的影响程度,提出了合理的路面层位设置、模量取值范围及路面结构组合,并通过某干线公路试验路段,验证了高模量沥青混凝土的抗车辙效果。
The article studied the anti-rutting performances of the high modulus asphalt concretes（HMAC） with various additions of PR/RA modifying agent,analyzed the impact de-gree on HMAC pavement anti-rutting performance of some factors,such as layer position,layer thickness,modulus,axle load,temperature and load frequency etc.,proposed reason-able pavement layer settings,range of modulus and pavement structure combination,and verified the anti-rutting effect of high modulus asphalt concrete through the experiment on a arterial highway.
