摘要
我国许多高速公路已经进入维修养护期,微表处理是一种经济且方便快捷的预防性养护方法。通过室内试验,分析了改性乳化沥青对微表处混合料性能的影响。特别提出了复配改性剂能充分发挥各自的优势,对微表处混合料高低温性能、耐磨性能、抗车辙等性能改善较为显著,提高了其社会效益。
Many expressways in China have entered into a period of repair and maintenance, and the micro-surfacing is an economic and convenient method for preventive maintenance. Here by laboratory tests, the analyses are made for the effects of modified emulsion asphalt on the mixture performance. Particularly, it is proposed that the compound modifiers could give full play to their advantages, and the high and low temperature performance, wearing resistance and anti-rutting performance of the mixtures in micro-surfacing would be improved significantly, thereby increasing the social benefits.
