水泥混凝土路面作为主要的路面结构形式从21世纪90年代以来在公路建设中得到飞速发展。但水泥混凝土路面的返修率较高,且返修时间较长,严重影响公路的使用,最严重的病害就是开裂破坏,如何防止水泥混凝土路面开裂无疑是一项重要且紧迫的任务。一、水泥混凝土路面开裂产生的原因导致水泥混凝土路面开裂的原因较多,通常有路基不均匀沉降、汽车严重超载、路面基层不合格、水泥混凝土本身质量问题、施工过程中水泥混凝土的收缩开裂为主进行分析。
Cement concrete pavement as the main form of pavement structure since the 1990s since the rapid development of highway construction. However, the rework rate of cement concrete pavement is high and the rework time is long, which seriously affects the use of the highway. The most serious disease is cracking and cracking. How to prevent the cracking of cement concrete pavement is undoubtedly an important and urgent task. First, the reasons for the cracking of cement concrete pavement Cause of cement concrete pavement cracking are many reasons, usually subgrade uneven subsidence, serious car overload, the road base failed, the quality of concrete itself, the construction process of concrete shrinkage cracking Lord for analysis.
