作为高级路面的水泥混凝土路面,以其稳定性好,抗滑性能好及养护费用低等优点越来越广泛被应用。在水泥混凝土路面修建技术不断提高的同时,路面也出现了开裂、断板、沉陷、错台等病害,给养护、修复带来了极大的困难,尤其是断板病害已经成为公路工程的通病之一,必须引起足够的重视,认真分析原因,积极采取措施加以防治。本文分析了水泥混凝土路面断板的原因,并提出了防治措施,从而有效地预防断板的出现。
As the advanced pavement, the cement concrete pavement is more and more widely used because of its good stability, good skid resistance and low maintenance cost. In cement concrete pavement construction technology continues to improve at the same time, the road also appeared cracking, broken plate, subsidence, the wrong Taiwan and other diseases, to conservation and repair has brought great difficulties, especially the broken board disease has become a common fault of highway engineering We must pay enough attention to it, carefully analyze the reasons and take active measures to prevent and cure it. This paper analyzes the reasons for the broken concrete pavement, and puts forward the control measures to effectively prevent the emergence of broken plate.
