摘要: 从高速公路沥青路面材料的再生利用出发,研究废旧沥青混合料中各种原材料的路用性能,以及沥青路面损害的原因及路面材料老化的机理.对原路面沥青混合料的筛分结果、骨料的性质以及原沥青与加入再生剂后沥青材料的性质进行了较为详细的研究与分析.结果表明:在旧沥青内添加适宜、适量的再生剂可以有效地改善旧沥青的路用性能,达到规范所规定的技术标准要求;提出了沥青路面混合料再生设计中应该注意的问题,对今后沥青路面的再生设计与施工具有一定的指导意义.

Abstract: Investigates experimentally the blacktop performance of high-speed way utilizing recycled asphalt mixture, as well as the cause of damage to blacktop and its aging mechanism. Discusses and analyzes in detail the sieving result of outspent asphalt mixture, properties of aggregate and especially the properties of the asphalt mixture in which the reclaiming agent has been added in the outspent one. The results show that the blacktop performance can be improved efficiently up to existing technical standard if adding properly the reclaiming agent in the outspent asphalt mixture. Some key points are suggested for designing recycled asphalt mixture as blacktop, which may be referable to the design and construction of utilizing recycled asphalt mixture.
