公路IMA耐久性沥青路面施工要点

Construction points of highway IMA asphalt pavement

为有效延长公路路面的使用寿命,满足日渐增长的重型车辆使用需求,雄安新区建材通道项目中采用IMA耐久性沥青路面(高稳定度增模剂改性)新型施工技术,同普通沥青路面相比,能有效增加面层抗裂能力,延缓车辙、坑槽等病害的发生。通过对公路工程中沥青路面新型材料的分析,简述了公路沥青路面控制要点,制定了提升沥青路面施工控制管理的措施。

In order to effectively extend the service life of highway pavement and meet the increasing demand of heavy vehicles,IMA durable asphalt pavement(high stability modifier)new construction technology is adopted in the building materials channel project of Xiong'an new area.Compared with ordinary asphalt pavement,it can effectively increase the crack resistance of surface layer and delay the occurrence of ruts,pits and other diseases.Based on the analysis of new asphalt pavement materials in highway engineering,this paper briefly describes the control points of highway asphalt pavement,and formulates the measures to improve the construction control management of asphalt pavement.
