水泥混凝土路面具有强度高,刚度大,稳定性好,使用年限长,养护费用少等优点。近几年应用比较广泛。但有些路面上出现了不同程度的断裂现象。关于混凝土路面的断裂问题,一直是困扰施工单位的一个通病。混凝土路面的造价高,工艺复杂,从路基基础、配合比、材料、施工、温度、养护等方面分析混凝土路面断裂产生的原因,并针对原因提出相应的控制措施。 Cement concrete pavement with high strength, stiffness, good stability, long service life, less maintenance costs. In recent years, more widely used. However, there are some road surface rupture to varying degrees. On the concrete pavement problems, has been plagued construction unit of a common problem. The cost of concrete pavement is high and the technology is complex. The reasons of concrete pavement rupture are analyzed from the aspects of subgrade, mix, material, construction, temperature and maintenance, and corresponding control measures are put forward according to the reasons.
