【摘要】：近年来，，国家大力发展公路交通行业，大范围新建、改建道路。在道路改建过程中会出现废旧路面材料的堆放和废弃，不仅造成场地紧张，资源浪费。冷再生技术很好地解决了场地问题、环境保护问题和节约资源问题，成为越来越受到关注的一门新技术。本文通过试验并结合以往研究成果，对冷再生材料和其他一些半刚性基层材料的性能增长规律进行了研究，获得了水泥稳定碎石和冷再生材料的劈裂强度及抗压回弹模量的范围。论文针对传统施工方法的不足，提出了一种新的摊铺方法即异步连续摊铺法。同时对底基层和基层采用异步连续摊铺法、基层和上基层采用异步连续摊铺法和底基层、基层和上基层采用异步连续摊铺法时，顶面弯沉和各层底面应力应变的最大值进行了力学分析，从而验证该方法的可行性。
[Abstract]:In recent years, the country vigorously development of highway transportation industry, a wide range of new and rebuilt roads. In road reconstruction will occur in the process of waste asphalt pavement materials and waste dumps, not only caused the nervous, the waste of resources. The cold regeneration technology is a good solution to the problem of space, environmental protection and conservation of resources, has become a new technology more and more attention.
In this paper, through the test and combined with previous research results, the law of growth of cold regeneration material and some other semi-rigid base material is studied, the cement stabilized macadam and cold regeneration material splitting strength and compressive modulus of the range was obtained. According to the shortage of traditional construction method, puts forward a new stand paving method of asynchronous continuous paving method. At the same time, subbase and base using asynchronous continuous paving method, and base on grassroots using asynchronous continuous paving method and subbase, base and base on the use of asynchronous continuous paving method, the top surface of the bottom surface deflection and the maximum of the stress strain of the mechanical analysis, to verify the feasibility of this method.
