SMA在高速公路养护罩面中的试验研究

Experimental research of SMA in highway maintenance

以金丽温高速公路2011年路面养护专项工程为依托,在金华方向K2563+650～K2652+648进行SMA-13沥青玛脂碎石混合料罩面试验路施工,分别从施工工序、施工主要工艺、施工检测三个方面进行研究,现场检测数据表明,该技术能有效抑制各路段原有病害的发展,一定程度上显现了其自身优点。

Based on 2011 Jin-Li-Wen highway maintenance special project,SMA-13 is used in road maintenance construction for test in the direction of Jinhua K2563＋650 ~K2652＋648.This paper is from the construction sequence,construction of main process,the detection of three aspects of research.Field test data shows that the technology can effectively inhibit the development of various sections of the original disease and its own merits to a certain extent.
