就地热再生技术在公路养护维修中的应用及跟踪检测

Application and tracking detection of in-situ thermal regeneration technology in highway maintenance

依托G6高速公路工程实际,对就地热再生技术应用情况进行持续3年的现场调研及跟踪检测。结果发现,就地热再生技术整体应用情况较好,有良好的经济和社会效益,但随着时间推移,路面出现了较多的横向裂缝和局部的纵向裂缝,需在后期持续跟踪检测,为其关键技术突破及推广应用提供技术支撑。

Based on the project of G6 expressway,the fi eld investigation and tracking detection on the application of in-situ thermal regeneration technology have been carried out for 3 years.The results show that its overall application is good and it has good economic and social benefi ts.However,with the passage of time,many horizontal cracks and local longitudinal cracks appear on the road surface,which need to be continuously tracked and detected in the later stage,so as to provide technical support for the breakthrough and popularization of its key technologies.
