经过多次反复试验 ,成功地开发了新型再生剂。以旧路改造工程为依托 ,对高等级沥青混凝土路面再生混合料的性能和设计方法进行了深入的试验和理论研究 ,大量的试验证明再生混合料的性能与旧料的掺配率和再生剂的用量有很大关系。提出了符合我国国情的再生混合料设计方法 ,为控制设计混合料的品质增加了一些验证性试验 After repeated experiments, successfully developed a new type of regenerant. Based on the old road reconstruction project, the performance and design methods of high grade asphalt concrete pavement recycled mixture have been deeply studied and theoretically studied. A large number of experiments have proved that the performance of the recycled mixture is similar to that of the old material, The amount of a great relationship. Put forward the design method of recycled mixture in line with China’s national conditions, adding some confirmatory tests for controlling the quality of the designed mixture
