水泥混凝土以其使用年限长、养护费用低等优点,在我国得到广泛应用,这对提高道路等级,改善道路通行能力,提高社会效益起到了明显作用。但是,随着水泥混凝土路面的增多,一些水凝混凝土路面因服役期已到或因设计不周、施工不当等原因造成路面出现各种病害(如断板、错台、唧泥等),且有些路面病害相当严重。现分析了旧水泥混凝土路面破损的产生原因,并提出了几种可供选择的修复方案。
Cement concrete is widely used in our country due to its long service life and low maintenance cost. This has played a significant role in improving the grade of roads, improving the capacity of roads and improving the social benefits. However, with the increase of cement concrete pavement, some of the pavement has some diseases (such as broken board, wrong station, pump mud, etc.) due to improper design and improper construction of some of the hydraulic concrete pavement, Some pavement diseases are quite serious. The reasons for the failure of the old cement concrete pavement are analyzed and several alternatives for repair are proposed.
