为了防治机场扩建工程沥青混凝土道面的反射裂缝,通过对道面接(裂)缝类型的分析,首先对原沥青混凝土道面裂缝如何进行处理提出了建议措施,然后对设置AC-5改性沥青吸收层、铺设APP改性沥青油毡、铺设玻璃纤维格栅和在新旧道面接缝处设置台阶等技术措施进行了研究,最后从水泥稳定基层和沥青混凝土面层施工两个方面探讨了需采取的施工措施,可为沥青混凝土道面接(裂)缝处理提供借鉴。
In order to prevent and control the reflection crack of the asphalt concrete pavement in the airport expansion project, the paper proposed some suggestions on how to deal with the crack of the original asphalt pavement by analyzing the type of the pavement crack. Then, Absorbent layer, the laying of APP modified asphalt linoleum, laying of fiberglass grille and the steps in the old and new pavement to set the steps and other technical measures were studied, and finally from the cement stabilized grassroots and asphalt concrete surface construction two aspects to be explored to be taken The construction measures can provide reference for asphalt pavement joint treatment.
