SMA沥青玛蹄脂碎石路面的工程质量控制

Engineering Quality Control of SMA Asphalt Mastic Crushed Stone Pavement

SMA沥青玛蹄脂碎石混合料是以间断级配的粗集料嵌挤形成骨架,以沥青、矿粉、纤维稳定剂以及少量的细集料组成的玛蹄脂填充骨架空隙所形成的一种新型沥青混合料,目前已在南通城市道路建设中广泛应用,南通经济技术开发区苏通大道小海北接线工程也采用SMA面层。该文介绍了该混合料在此工程施工中的质量控制过程。

SMA asphalt mastic crushed stone mixture is a new asphalt mixture formed by the gap-graded coarse aggregates inlaid into skeleton and the skeleton gap filled with the mastic composed of asphalt, mineral powder, fiber stabilizer and small-quantity fine aggregates. It has been widely used in the road construction in Nantong City. SMA surface course is also used in Xiaohaibei Connecting Line Project of Sutong Street in Nantong Economic Technical Development Zone. The article introduces the quality control process of this mixture in the project.
