高速公路改扩建路面检测评价及裂缝处置技术研究

Study on Evaluation and Evaluation of Highway Pavement Reconstruction and Expansion and Crack Treatment Technology

随着社会经济发展,沥青高速公路改扩建工程势在必行,裂缝病害会对路基结构强度造成影响,对高速公路进行路面检测评价以及裂缝修补技术研究显得尤为重要,通过文献查阅总结、对文献进行理论分析、具体的现场试验,结合现场施工情况总结得出以下结果:总结了路面裂缝的种类;对路面状况进行了检测及评价,路段整体评价较好,且病害以裂缝为主;经过对该路段研究分析,得出了该段路面产生裂缝的原因,根据实际工程状况制订了施工方案,为其他工程提供了经验。

With the development of society and economy,the reconstruction and expansion of asphalt highways is imperative.Cracks will affect the strength of the roadbed structure.It is especially important to carry out road inspection and evaluation of highways and research on crack repairing technologies.Theoretical analysis,specific field tests,and site construction are summarized to obtain the following results:the types of road cracks were summarized;the road conditions were detected and evaluated,and the road sections the overall evaluation is good,and the disease is mainly cracks.After researching and analyzing the road section,the cause of cracks in the road surface is obtained,and the construction plan is formulated according to the actual engineering conditions,which provides experience for other projects.
