Study Of The Typical Distress And Cause Of The Cement Concrete Pavement In Cold Regions

The cement concrete pavement obtained the widespread use in our country. Butpart of the cement concrete pavement in the use of5-8years began to appear a largenumber of diseases, some even earlier, a large number of old cement concrete pavementalso faces the problem of damage repair, and the analysis of the causes of pavementdisease is one of the key steps, according to the Jilin province transportation science andtechnology plan projects the cold areas of rural highway cement concrete pavementrepair key technology research, pay attention to the development of the pavementdisease research, combined with field investigation and test data, to analyze therelationship between the disease, a study of the causes of the damage, the maintenancework plays a guiding role.In this paper, combined with traditional Chinese medicine in the "concept ofwholism" and " determination of etiologic factors based on differentiation " thought andsystem of classification methods to classify the cause of cement concrete, by using themethod of intersection of different subject, providing theoretical basis for disease, theanalysis of the causes. Through the mechanism of concrete pavement diseases anddisease development process analysis, get the links between diseases and the chainrelationship disease by using the theory of disaster chain. Investigating and analyzingthe cement concrete pavement in the cold region disease through spot field investigation,achieving the region’s main pavement disease types and influencing factors. Usingdisease chain theory to analysis the law of development of diseases, the connectionbetween them and various factors how to influence on the diseases. Achieving the causeof cement concrete typical disease in the region.Using the AHP analytic hierarchyprocess (AHP) to analyze pavement diseases chain. Using the method of “cut off thedisease chain” to repair pavement disease.In this paper, we get the cause of cement concrete system classification, diseasechain theory. And apply to the cold areas of cement concrete pavement disease causesanalysis, get the development process of the typical pavement diseases and causes in theregion, the diagnosis model of chain analysis disease development in the later period,combined with the existing pavement diseases repairing method, and puts forwardtreatment measures for prevention and control of broken chain.
