高速公路SMA沥青混凝土路面配合比设计及施工应用

Design and Construction Application of SMA Asphalt Concrete Pavement Mix Ratio in Expressway

为进一步提升SMA沥青路面的使用性能,对SMA-13沥青玛蹄脂碎石混合料配合比进行设计,结合具体工程,对SMA-13沥青玛蹄脂碎石施工工艺研究,对施工准备、沥青混合料拌和、沥青混合料摊铺、沥青混合料碾压、沥青混合料养护等施工要点进行具体阐述。

In order to further improve the use performance of SMA asphalt pavement,the SMA-13 asphalt asphalt gravel mixture was designed,combined with the specific project,the construction technology of SMA-13 asphalt asphalt gravel was studied,elaborates the construction preparation,asphalt mixture mixing,asphalt mixture paving,asphalt mixture rolling,asphalt mixture maintenance and other construction points.
