  要:由于SMA沥青混合料具有“三多一少”的特点,即:粗集料多、矿粉多、沥青多、细集料少”。因此,在SMA沥青路面施工中需做好施工质量控制,如控制不严格,沥青路面较易出现泛油、车辙等问题。本文结合SMA-13沥青路面施工,从原材料、施工前的准备、沥青路面施工等关键控制环节介绍了SMA沥青路面施工技术的要点,为SMA沥青路面施工质量控制提供借鉴和参考。

Abstract: Because SMA asphalt mixture has the characteristics of " three polys and one little", that is more coarse aggregate, more mineral powder, more asphalt and less fine aggregates. If the control is not good in the construction, it is easy to lead to problems such as flooding oil and rutting. So combined with smA-13 asphalt pavement projects, the main points of construction of pavement was introduced from the selection of raw materials, the preparation before construction, transportation, paving, roller compaction and other key paving processes.etc. The results of this paper could provide references for the implementation of similar projects.

Key words:SMA-13; asphalt pavement; construction
