摘　　要：针对大量国省公路和农村公路需要进行薄层加铺预防性养护和功能恢复与提升的实际需求,以及沥青加铺层混合料对车辙和反射裂缝的要求,遵循抗车辙和抗裂性能平衡的原则,设计了一种基于岩沥青和骨架结构以及高沥青含量的低成本沥青混合料(RAC),并进行了室内性能评价。检测结果表明,RAC各项性能均优于基质沥青混合料,与SBS改性沥青混合料性能相当,但成本大幅降低。According to the actual demand of thin overlay for preventive maintenance and functional recovery and improvement of a large number of national and provincial highways and rural roads, as well as the requirements of rutting and reflective cracking resistance of the asphalt mixture, following the balance principle of both rutting and crack resistance performance, through this study, a low-cost asphalt mixture(RAC) has been designed based on rock asphalt, skeleton structure and high asphalt content, and laboratory performance evaluation has been conducted. The test results have shown that the performance of RAC is better than that of matrix asphalt mixture and comparable with SBS modified asphalt mixture, with the cost being greatly reduced.
