摘　　要：沥青玛蹄脂碎石SMA路面在国内外公路工程中被大面积推广应用,但SMA路面渗水现象始终未得到有效解决;同时SMA路面渗水成因尚不明晰,极大制约了该项技术的应用发展。研究依托山西省多条高速公路SMA路面工程检测项目,深入分析引起SMA路面渗水现象的原因,进一步提出解决SMA路面渗水问题的相关技术措施,为提升SMA路面的施工质量提供技术支持。The stone mastic asphalt(SMA) pavement has been widely promoted and used in domestic and foreign highway engineering, however, the water seepage in SMA pavement has still not been effectively solved, and its cause is not clear, which greatly restricts the application and development of SMA pavement.Based on several SMA pavement engineering detection projects of Shanxi Provincial expressways, this paper analyzes the causes of the water seepage in SMA pavement in depth, and further proposes relevant technical countermeasures for this problem, which can provide technical support for improving the quality of SMA pavement construction.
