一、前言沥青路面的再生利用技术是将各种受到破坏、不能满足行车要求而需维修的沥青路面,经开挖、破碎,并重新拌制,压实而用作路面基层或面层材料的工艺过程。沥青路面的再生利用,可以节省能源、节约材料、降低造价。因此,近年来国内外都广泛地开展了试验研究工作,并得到了迅速发展。我区从1979年开始对旧油石重复利用进行试验研究,1982年开始再生利用并取得可喜成果,但是由于采用热拌工艺,设备昂贵,不易机械化,人工工效低,强度大,节能效果差。阳离子乳化沥青路面施工工艺试验成功,为冷
I. Introduction Asphalt pavement recycling technology is to be destroyed, can not meet the traffic requirements and maintenance of asphalt pavement, excavation, crushing, and re-mixing, compaction and used as the pavement base or surface material crafting process. Recycling of asphalt pavement can save energy, save materials and reduce costs. Therefore, in recent years, experimental research has been carried out extensively at home and abroad and has been rapidly developed. Since 1979, our district began to experiment on the reuse of used asbestos. Since 1982, it has started to recycle and achieved gratifying results. However, due to the hot mixing process, the equipment is expensive, difficult to mechanize, has low labor efficiency, has great strength and has poor energy-saving effect. Cationic emulsified asphalt pavement construction technology test was successful, as cold
