粗粒式沥青混合料施工技术研究

Research on Construction Technology of Coarse Asphalt Mixture

以桑宝一级公路沥青混凝土面层实体工程为依托,探讨了AC-25C型粗粒式沥青混合料的生产配合比设计方法,对混合料的拌和、摊铺及碾压等施工技术进行了具体的研究,确定了AC-25C型粗粒式沥青混合料的施工工艺和过程控制方法。

In the study,the production mixture ratio of AC-25C coarse asphalt mixture was studied.Especially,the construction technology,including the mixing,spreading and rolling,was analyzed.Finally,the construction technology and the process controlling method of AC-25C coarse asphalt mixture were given.All those were based on the actual project which was the asphalt pavement from Sagendalai to Baochang primary highway system.
