真空灌浆技术在水泥混凝土路面施工中的应用

水泥混凝土路面是我国公路路面主要形式之一,在我国公路网构成中占有较大比重。它具有强度高、刚度大、受温度影响小、使用寿命长等优点。但水泥混凝土路面接缝较多,对超载较为敏感,易发生脱空、唧泥、裂缝等先期病害,从而导致路面的破损。如何治理与预防脱空、唧泥等病害,搞好水泥混凝土路面的养护,延长公路的使用寿命,改善其通行能力,具有十分重要的意义。

The Application of Vacuum Grouting Technology in Cement Concrete Pavement Construction

Cement concrete pavement is one of main form of road surface in China, it accounts for a large proportion of road network in China. It has advantages of high strength, rigidity, little affected by temperature, and long life. But the cement concrete pavement is more sensitive to the overload, prone to separation, mud, cracks early disease, leading to road damage. How to control and prevent separation, pumping diseases, improve the conservation of cement concrete pavement, extend the life of the highway, improve its capacity are of great significance.
