A Study Of The Causes Of Lian Yi Expressway JRCP Pavement Typical Diseases And Its Maintenance Measures

JRCP（Jointed Reinforced Concrete Pavement）have greater rigidity, stronger diffusionload stress capability, greater stability, lower requirements to the grassroots, longer life, lessmaintenance costs and conducive to driving at night than other roads. Therefore, it has beenwidely used in today’s highway construction. A large number of cement concrete pavementcompleted in a very short time, there will be a lot of roadbed and road surface disease. Even ifwe were timely maintenance and repair, the disease is still recurring. This reality formed totransport a lot of inconvenience to the maintenance and construction of new problems.Therefore, we carried out a study of the causes of Lian Yi Expressway JRCP pavement typicaldiseases and proposed the effective maintenance and repair decisions。This has a veryimportant reality role and long-term significance to effectively extend the life of the cementroad and improving cement pavement performance.In order to investigate the reasons of the JRCP Pavement Distress, and analysis of itsmechanism, This article is relying on engineering examples of Lin Yi Expressway JRCPpavement. We first selected a representative test point, and then carry out a lot of research,field trials and indoor soil test research. Finally, I would Mathematical Statistics andmechanical analysis of test data. The face of reality had little effect of Lian Yi HighwayMaintenance in recent years, The article eventually analyzed the root causes of JRCPpavement diseases, and reveals the mechanism of its formation. Finally, the authors putforward suggestions for road maintenance and proposed a reasonable solution for the overhaulengineering of Lian Yi Expressway JRCP pavement.The results of this research to further improve the cement concrete pavement, inparticular, the causes of JRCP pavement typical diseases. It provide a realistic basis for JRCPpavement design and conservation norms.
