摘要
SMA4.75沥青混合料在薄表层应用中具有相当优良的使用性能,在各类预防性维护项目中具有良好的前景。对SMA4.75沥青混合料进行配合比设计试验,着重从原材料试验、集料规范、混合料体积设计和最佳油石比设计等方面进行研究,并最终将其应用于西部高寒地区高速公路。
The SMA4.75 asphalt mixture had an excellent performance in surface layer, and thus had a bright future in some kinds of preventive maintenance projects. In this paper, the SMA4.75 asphalt mixture design had been done, and empha- sis was put on several sides, such as raw materials experiment, aggregate standards, mixture volume design and optimal asphalt content design. The work here had already been used on the expressway of rigid cold resign in western China.
