浅谈道路病害成因防治和改扩建工程接缝处理
摘要
通过这次顶岗实习，了解了道路改扩建工程的定义、特点、意义、适用条件、目的和基本任务、工作内容、建设程序；道路进行改扩建工程的依据；道路的改扩建工程中还有待于提高和完善的方面；与此同时知道了改扩建工程与大修工程的区别。
通过对原有的破坏路面的观察和研究，对沥青混凝土路面早期病害的类型、成因进行了分析，并对预防措施进行了探讨。
在改扩建工程施工过程中，对新旧路路基接缝问题也有了一定的了解，在施工时要把接缝处做成台阶形，然后边坡的土慢慢的收回来，以达到要求的坡度为止。
在工程施工中如何才能使路线较长的工程的质量得到保证也有浅略的涉及，从质量保证、工期保证两方面谈起。

Abstract
Teaching Practice through this to understand the way for the reform and expansion project definition and characteristics of significance and conditions, objectives and basic tasks, the contents of the work, construction procedures; road for reform and expansion project basis; road renovation and expansion project has yet to improve and perfect; Meanwhile know that the reform and expansion project and the major repair works distinction.
Based on the original road damage to the observation and study of asphalt concrete pavement early disease types, Analysis of the causes and preventive measures were discussed.
Extension works in the construction process, the old road roadbed joints also have a certain amount of understanding, Construction at the 毕业论文http://www.751com.cn/ 论文网http://www.751com.cn/
Construction of the project how to make a longer route of the project of the quality assurance is also involved in the shallow slightly, from the quality assurance, Time guarantee about two aspects.
