摘要
采用"干法"工艺,将路用木质纤维、废橡胶粉两者以一定的掺量、工艺共同使用,以提高沥青混凝土的路用性能。试验研究表明,采用沥青马蹄脂(SMA)级配的纤维胶粉复合改性沥青混合料,具有良好的路用性能。此方法工艺简单,能充分发挥两者的优点,减少环境污染,推进废旧轮胎、废旧纸张的回收利用,具有较高的经济和社会效益。
In order to improve the performance of pavement materials , a technique of dry mixing crumb rubbers and xylon fiber in asphalt mixture is used in laboratory. The experiment research indicates that it can improve the stability for SMA pavement of the compositly modified asphalt concrete by making use of the advantages of the fibers and the rubbers and the craft is simple . Moreover it is a good pavement material of decreasing environment pollution and has remarkable economic and social benefit, which will promote to recycling of waste tire and waste paper.
