公路工程施工中改性沥青SMA路面施工技术的应用探析

在公路工程施工中,SMA路面施工技术应用广泛,这项技术主要以SMA沥青玛蹄脂料为主,这种混合料的主要成分有矿料骨架、沥青、矿粉、纤维稳定剂等,将这种材料用于公路路面施工中,可以起到良好效果。由于这种材料耐久性高,所以成为了公路路面施工的首选材质。文章主要介绍了改性沥青SMA混合料结构特征,分析了改性沥青SMA路面设计要点与实际施工中具体的技术操作要点,希望能够为我国公路工程发展提供参考。

In highway engineering construction,SMA pavement construction technology is widely used.This technology is mainly Stone Mastic Asphalt(SMA),the main components of this mixture are mineral skeleton,asphalt,mineral powder,fiber stabilizer and so on.Good results can be achieved when this material is used in highway pavement construction.Because of its high durability,this material has become the preferred material for highway pavement construction.This paper mainly introduces the structural characteristics of modified asphalt SMA mixture,and analyzes the key points of modified asphalt SMA pavement design and specific technical operation in actual construction,hoping to provide reference for the development of highway engineering in China.
