乳化沥青灌浆技术在公路路面板底脱空中的应用

板底脱空是公路路面的一种常见病害.以板底脱空为研究对象,对板底脱空的产生原因、机理、乳化沥青灌浆材料及施工工艺等关键技术进行研究,采取灌浆技术进行治理,具有施工工艺简单、附属设备少、施工方便等特点,对公路畅通影响较小.研究成果可以有效地指导公路路面板底脱空治理,具有一定的工程应用价值.

Application of Emulsified Asphalt Grouting Technology to Void under Pavement Slab

Void under pavement slab is a common disease. Taking the void under pavement slab as an object of study, key technologies such as the void reasons, void mechanism, emulsified asphalt grouting material and construction technology are studied. Grouting is taken to dispose this disease, which has such advantages as simple technique, less auxiliary equipments, convenient construction, has less negative influence towards the traffic. The research results can guide the treatment of the void under pavement slab effectively, and play an important role in the practical project.
