摘　　要：在双层SMA桥面铺装中设置SMA-5沥青胶砂防水层。通过对沥青胶砂拌和、摊铺和碾压性能的施工技术研究,解决桥面平整度、局部渗水、铺装腐蚀等问题。SMA -5 asphalt sand is designed to be used for bridge deck waterproofing layer where double - layer SMA structure is used on the deck pavement. The problems such as deck evenness, Local water seepage, pavement erosion and so are to be solved by studying the construction technology of mixing, paving and compaction functions for SMA -5.
