水泥混凝土路面断板原因及处理措施

[摘要]

水泥混凝土路面产生连续断板及后期断板产生的原因及处理措施,在施工过程中使用一些特殊的施工方法,造成干缩、冷缩裂缝并形成断板。对断板产生的原因就当时的施工的各种原因进行分析,并提出以后工作应注意的问题,以防止类似的现象的再次发生。随着高等级公路的迅速发展,对于路面平整度要求越来越高,路面平整度的合格率既反映了行车舒适程度,又反映了施工队伍的水平。近三年,某些单位所施工水泥砼面板有相当部分如开裂、断板、沉陷、错台,本人就出现的某些现象借此分析、初探水泥混凝土路面的施工、破坏原因及处理措施。

[Summary]
The reason that the disconnected board produce of disconnected board and later stage and processing measure produce continuously in the concrete road surface of cement, use some special construction method in the course of constructing, cause, do, contract, not cold to contract the crack and form to break the board. Analyze on various reasons of the construction at that time in breaking the reason why the board produces, the question that the work should be paid attention to after putting forward, in order to prevent the recuring of similar phenomenon. With the rapid development of the superhighway, it is higher and higher to the roughness requirement of road surface, the comfortable intensity that the qualification rate of the roughness of road surface has reflected and driven a vehicle, has also reflected the level of the operation team. In the past three years, some units of cement concrete panels constructed have had a great part such as fracturing, broken and sti
