公路加宽改建工程路面纵向开裂原因及对策研究

Research on the Causes and Countermeasures of Longitudinal Cracking of Road Surface in Highway Widening and Reconstruction Engineering

公路加宽改建工程是现代交通建设的必然选择,但随着交通量的不断增加,路面纵向裂缝的出现给公路的使用带来了很大的安全隐患,对道路交通的正常运行也造成了严重的影响。文章通过对公路加宽改建工程中路面纵向裂缝的形成机理进行分析,总结其主要原因,并针对性地提出了有效的预防和治理措施,为公路加宽改建工程的设计、施工及养护提供一定的参考。

Highway widening and reconstruction engineering is an inevitable choice for modern traffic construction.However,with the continuous increase of traffic volume,the emergence of longitudinal cracks on the road surface has brought great potential safety hazards to the use of highways,and also has serious impact on the normal operation of road traffic.Through the analysis of the formation mechanism of longitudinal cracks on the road surface in highway widening and reconstruction engineering,the main reasons are summarized,and effective prevention and treatment measures are put forward,which provides some reference for the design,construction and maintenance of highway widening and reconstruction engineering.
