1、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层次：专科起点本科专业：土木工程（道桥方向）年级：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
2、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AbstractAlongwithourcountryhighwayconstruction'sdevelopment,theasphaltcoagulationearthenroadpavementasaresultofhasthesurfacing,thedrivingcomfortab
