Study on Quantitative Evaluation Method of Treatment Effectiveness on Cement Concrete Pavement Distress
Publication: Road Pavement and Material Characterization, Modeling, and Maintenance
Abstract
In order to promote the technological element in decision-making of pavement maintenance management, a quantitative evaluation method for treatment effectiveness of maintenance activities on jointed concrete pavement was proposed through analyzing historic maintenance data in pavement maintenance management system. In order to verify the correctness of the method, the historic maintenance data of Xiangtan-Leiyang Expressway were analyzed to calculate the treatment effectiveness of void beneath pavement can be repaired by slab undersealing with different injected materials. After a series of statistical analysis, the treatment effectiveness of slab undersealing using cement grout was 75.8%, and the treatment effectiveness of slab undersealing using emulsified asphalt was 84.4%. According to this quantitative analyzing result, the current unit price of slab undersealing using emulsified asphalt grout is too high to popularize, its reasonable unit price is recommended as 21.4 yuan/m2.
