| 摘 要： | 结合某高速公路沥青路面热再生工程的实际情况,测定旧沥青的常规指标、粘度及组分并与原新沥青各指标进行对比,评价旧沥青的老化程度.选择不同种类再生剂,以不同比例调配旧沥青组成再生沥青,观察再生沥青的常规指标、粘度及等性能的变化情况.试验结果表明,在旧路面的老化沥青中掺入10%～30%再生剂后,其性能得到明显的改善.

| Abstract: | Concerning the actual situation of the expressway,by testing and comparing with the date of softening point,penetration,ductility,viscosity and composition in used and new asphalt,it can be evaluated the degree of aging in the used asphalt.Different kinds of recycling agents are selected,use different ratio of recycling agents to get recycling asphalt is used and take a series of experiments are carried out to on the changes of its conventional indicators,viscosity and so on.The test results show that addin... |
