对公路改性沥青路面施工质量管理探讨

Quality Management of Modified Asphalt Pavement Construction

改性沥青及SMA路面结构在重交通作用下具有良好的抗车辙能力,其特点可归纳为三多一少:沥青多;矿粉多;粗集料多;细集料少,使用改性沥青掺纤维稳定剂,材料品质要求高,施工技术性强,为保障施工质量必须从源头材料和配合比设计及施工工艺加强控制。

Modified asphalt and SMA pavement structure under the action of the heavy traffic has good resistance to rutting,and its characteristics can be summarized as follow： asphalt is much;slag is much;coarse aggregate is much;fine aggregate is less.Modified asphalt doped fiber stabilizers,materials are high-quality,and construction technology is high.We must strengthen control from source material and mix design and construction techniques for protecting the quality of construction.
