沥青混凝土路面再生利用试验分析

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。

Test and Analysis of Recycled Mixture for Old Pavement

It is a new topic that the recycling of high grade asphalt pavement is utilized presently in china. The new-style recycling agents are exploited successfully by many tests. Based on the old pavement reclaimed projects, the performances and designing method of the recycled mixture of the high grade asphalt pavement are studied, many tests show that the performances of recycled mixturs are connected mostly with the proportion of old mixtures and recycling agents. A new designing method of recycled mixture is presented and its construction method are discussed according to the present status of mixing field in our country.
