摘　　要：目前国内针对冷补沥青混合料的性能评价方法不尽合理,需要根据冷补沥青混合料的特点提出相应的性能评价方法和技术标准。针对冷补沥青混合料的特点分别从车辙试验、单轴静载蠕变试验、劈裂强度试验、抗压回弹模量试验和低温工作度试验评价冷补沥青混合料的性能,提出冷补沥青混合料的性能评价方法及技术要求。At present,the performance evaluation method of cold patch asphalt mixture in China is not reasonable,so it is necessary to put forward corresponding performance evaluation methods and technical standards according to the characteristics of cold patch asphalt mixture.According to the characteristics of cold patch asphalt mixture,the performance of cold patch asphalt mixture is evaluated from rutting test,uniaxial static load creep test,splitting strength test,compressive rebound modulus test and low temperature working degree test,and the performance evaluation methods and technical requirements of cold patch asphalt mixture are proposed.
