干法复合改性提高沥青路面耐久性能研究

采用干法复合改性技术,在沥青混合料拌和过程中直接掺加,因而施工工艺非常方便易行,不用添加新的机械设备,易于推广应用。采用的复合改性剂是目前改性剂的各项优点之集成,具有不提高沥青混合料的拌和、摊铺、碾压等施工温度,不改变沥青路面施工工艺,且能使沥青混合料的高温、低温及抗水损害等耐久性得到显著提高。

Research on dry composite modifier improving durabilityof asphalt pavement

Dry composite modifier is to add modifier in mixing process of asphalt mixture,so the construction technology is very convenient without adding new mechanical equipment and is easy to popularization and application.The adoptive composite modifier is the integration of all merits of current modifiers,and it can improve high temperature,low temperature and water-resistance durability of asphalt mixture without increasing construction temperature and changing construction technology.
