摘　　要：为了验证厂拌热再生沥青混合料的低温和抗水损害性能,在旧料掺量为30%的再生混合料配合比设计的基础上,进行了劈裂试验、冻融劈裂试验、冻融循环试验等路用性能试验研究,同时设计相同级配的全新料作为对照组。试验结果表明,旧料掺量为30%的再生料低温和抗水损害性能与全新料的性能相差不大,满足使用性能要求。In order to verify the low temperature and water damage resistance of the mixed reclaimed asphalt mixture,the splitting test and freeze-thaw splitting test were carried out based on the mixture design of the recycled material with 30% of the old material.The road performance test,such as freeze-thaw cycle test,was carried out,and the same grade of new material was designed as the control group.The test results show that the low temperature and water damage resistance of the 30% recycled materials have little difference with the performance of the new materials,which meets the performance requirements.
