- 摘要:
- 目前天津港港区内大部分道路为水泥混凝土路面,在使用过程中车辆超载十分严重,此外由于路基处理及混凝土本身原因或施工缺陷,常导致混凝土路面发生局部破损,大大缩短了道路的使用寿命。作者通过近些年水泥混凝土道路工程施工的实践经验,针对路面常见的几种裂缝表现形式,对其产生的原因、预防措施和维修方法进行分析论述。
Most roads in Tianjin Harbor zone have concrete pavement. The local breakages of the concretepavement occur frequently owing to serious vehicle overloads or pavement defects induced by improperroadbed treatment, concrete quality and construction process, which lead to shorten the road service life obvi-ously. In combination with the practical experience from cement concrete road construction in recent years,this paper analyzes several common patterns of pavement cracks and their causes, as well as prevention mea-sures and maintenance methods.2009,5(5): 66-68 收稿日期:2009-7-9分类号:U416.216作者简介:孙占旺(1971-),男,天津人,工程师,毕业于长沙理工大学.现从事工程技术管理工作。参考文献:
