摘要
为推动公路沥青路面建设技术的进一步发展,文章总结了高模量剂改性机制,以江阴靖江长江隧道JJSD-21 标北接线路面工程为研究对象,探讨了高模量剂掺量对沥青混凝土静态回弹模量、高温稳定性、疲劳性能的影响.同时.在高模量沥青路面钻芯取样,利用压实度评价了其路用效果,研究成果可为类似项目提供借鉴.
Abstract
In order to promote the further development of highway asphalt pavement construction technology,this paper summarizes the modification mechanism of high modulus agent.Taking Jiangyin Jingjiang Yangtze River Tunnel JJSD-21 section north connection line pavement engineering as the research object,the influence of high modulus agent content on static rebound modulus,high temperature stability and fatigue performance of the asphalt concrete is discussed.At the same time.The core sample drilling of high modulus asphalt pavement is carried out,and the road effect is evaluated by compaction degree.The research results can provide reference for similar projects.
