Continuously Reinforced Concrete Pavement(CRCP) has been widely used throughout the world due to the merit of no jonint related problems as in Jointed Concrete Pavement. In this project, crack width, crack spacing, crack shape, and failure were surveyed. Surveyed results were compared with AASHTO CRCP steel design criteria and that of several CRCP test sections constructed in the United States. It was found from the comparison that most of the CRCPs surveyed met the AASHTO criteria in terms of crack spacing and crack width and that Korean CRCP was in pretty good condition in terms of crack shapes and failures. Deflection test with Dynafeict is accomplished and the structural capacity of CRCP is better than that of JCP. As the alternative plan of material improvement, the labolatory test of fly ash as useful admixture is accomplished. The correlation of accumulative traffic load and crack width is presumed with regression analysis.
