基于温度损失的城市道路改造加铺SMA-13施工控制

On construction control over reconstruction and overlay of SMA-13 on urban roads based on temperature loss

结合工程实践,详细介绍了用于城市道路沥青路面改造加铺层的SMA-13沥青混合料的配合比设计以及施工质量控制,从材料选择、技术指标、配合比设计以及施工关键措施等方面阐述了SMA-13路面施工质量控制技术,对城市SMA沥青路面加铺改造具有一定的借鉴意义。

Combining with the engineering practice,the paper introduces the mixing ratio design and the construction quality control of the SMA-13 asphalt mixture,the reconstruction overlay of the asphalt roadbeds on urban roads,and illustrates the quality control technique for SMA-13 roadbed construction from the material selection,the technical indexes,the design for the mixing ratio,and the key measures for the construction,so as to provide some reference for the overlay reconstruction of SMA asphalt roadbed in cities.
