沥青路面再生利用试验分析

沥青路面再生利用试验分析 English Version

摘要: 高级沥青路面的再生利用 ,在国内还是一个崭新的课题。经过多次反复试验 ,成功开发出了新型再生剂。以旧路改造工程为依托 ,对高等级沥青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 ,为控制设计出的混合料的品质而增加了一些验证性试验

Abstract: It is a new topic on the recycling of high grade asphalt pavement presently in china.Firstly,new recycling agents have been exploited successfully by many tests.Secondly, based on an old pavement projects,the performance and design method of recycled mixture of high grade asphalt pavement have been studied by many tests.The test results show that the performance of recycled mixture is dependent mostly on the proportion of old mixture and recycling agent.A new design method of recycled mixture has also been proposed.Finally,the construction method of recycled mixture according to its present status in our country is discussed.
