沥青路面纵向裂缝注浆施工技术研究

Analysis of Grouting Technology for Longitudinal Cracks in Asphalt Pavement

20世纪以来我国各级政府交通运输部门对原有的低级别、性能落后的老旧公路进行大规模的建设改造,通过改造极大缓解道路拥堵状况,助力经济社会的快速发展。在公路建设过程中,设计者本着节约土地资源的原则在公路改造过程中对大量现有公路项目采用沿老路拓宽改造,部分线形要素无法满足的路段进行微调,充分利用老路节省了土地资源,保持沿路群众的生产生活,提高车辆通行能力及行车便利性。通过一段时间的运行观察,由于施工组织管理及地质原材料等方面的原因,在道路加宽新旧结合处出现沿加宽施工缝的纵向裂缝,严重影响道路使用效果,且处理难度大,效果差。借助工程实例介绍如何对沥青路面老路加宽处出现的裂缝处理以及处理后的效果。

Since the beginning of twentieth Century the department of transport of our government at all levels of the low level, behind the performance of large-scale transformation of the old highway construction, through the transformation of greatly ease road congestion, boost the rapid development of economic society. In the process of highway construction, the designer can save the principle of land resources in the transformation process of a large number of highway projects using the existing highway along the old road widening, road alignment elements cannot satisfy the fine-tuning principle, make full use of the old saves land resources, more keep along the people＇s production and life, improve the traffic capacity and traffic convenience of. By running a long time observation, due to construction organization and management and other aspects of the geological materials, the combination of old and new road widening occurred at the longitudinal crack along widening construction seam, serious impact on road use effect, and the processing difficulty is big, bad effect. This paper introduces how to deal with the cracks in the old road widening of asphalt pavement and the effect after treatment with the help of Engineering examples.
