水泥砼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。但水泥砼路面接缝较多,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,搞好水泥砼路面的养护,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。 Cement concrete pavement is one of the main forms of highway pavement in our country, accounting for a large proportion of the composition of our country’s road network. It has the advantages of high strength, high rigidity, small temperature influence and long service life. However, more cement concrete pavement joints are more sensitive to overload, prone to cavitation, mud, cracks and other pre-disease, resulting in road damage. How to control and prevent such problems as emptying, pumice and muddy diseases, improving the maintenance of cement concrete pavement, prolonging the service life of the highway and improving its traffic capacity are of great significance.
