随着公路建设的迅猛发展,水泥混凝土被大量应用于公路路面,但通过近些年的使用情况来看,水泥混凝土路面的建筑质量并不尽人意,由于质量差造成维修间隔时间短,大大增加了建设费用。水泥混凝土路面产生质量问题的原因除路基和路面基层施工质量达不到设计要求外,主要还有路面面层施工不规范及组成材料不合格的问题。为了能更好地控制水泥混凝土质量,下面针对常见的公路水泥混凝土路面质量问题作一些探讨。
With the rapid development of highway construction, cement concrete is widely used in highway pavement. However, the construction quality of cement concrete pavement is unsatisfactory according to the usage in recent years. Due to poor quality, the maintenance interval is short and greatly increased The construction costs. Cement concrete pavement causes quality problems in addition to roadbed and pavement construction quality failed to meet the design requirements, there are mainly non-standard construction of pavement surface and the composition of the material failed. In order to better control the quality of cement concrete, the following for some common highway cement concrete pavement quality problems to make some discussion.
