大连理工大学网络高等教育 本科生毕业论文（设计） 题目: 沥青混凝土路面裂缝问题分析 学习中心：内蒙古阿拉善奥鹏学习中心 专科起点本科 专 业： 土木工程（道桥方向 2011年春季 学 号： 111129304195 学 生： 刘雄鹰 指导教师： 乔 娜 完成日期： 2013年9月2日  内容摘要 随着交通的发展，道路越来越成为人们所关注的话题，在这里就以我实习经历以及所查文献，对沥青路、混凝土路、沥青混凝土路做出对裂缝的预防与治理措施。 这里颇重沥青路面的防治，在堤防道路使用期开裂是普遍存在的问题，且不论其基层是柔性的还是半刚性的。路面裂缝的危害在于从裂缝中不断进入水分，使基层甚至路基软化，导致路面承载力下降，产生唧浆、台阶、网裂、纵缝等病害，从而加速路面破坏，影响堤防道路完整，对防汛抢险交通不利。文章从裂缝产生的原因入手，对沥青路面层间应力、堤身问题进行分析，并提出预防裂缝出现的相应措施。 关键词：沥青　　裂缝　　成因及预防　　堤防道路 Abstract Along with our country highway constructions development, the asphalt coagulation earthen road pavement as a result of has the surfacing, the driving comfortably, wear-resisting, the noise to be small, the construction cycle is short, maintenance service simple and direct and so on characteristics, but more and more is applied in the first-class highway construction, but the asphalt coagulation earthen road pavements crack question one to puzzles is maintaining, the constructors. The bituminous pavement in the embankment path lifetime dehiscence is the universal existence question, no matter and its basic unit is flexible or semi-rigid. Surface checks harm lies from the crack enters the moisture content unceasingly, causes the basic unit even roadbed to soften, causes the road surface supporting capacity to drop, produces squirts plant diseases and so on thick liquid, stair, net crack, longitudinal seal, thus the acceleration pavement failure, affects the embankment path to be complete, is disadvantageous to the flood fighting transportation. The bituminous pavement crack question is one of highway engineering quality common failings, has the reason from the crack to obtain, the stress has carried on the detailed analysis to the asphalt pavement layer, and proposed target-oriented the prevention crack appears corresponding measures. the bituminous pavement in the embankment path lifetime dehiscence is the universal existence quest
