A Performance Evaluation of the Continuously Reinforced Concrete Pavement in Korea through Field Condition Surveys

A performance evaluation study of the Korean Continuously Reinforced Concrete Pavements (CRCP) was conducted through field condition surveys. The survey items included crack width, crack spacing, and steel stress which are the AASHTO CRCP performance criteria. Surveys were conducted on the several locations of the Kyongbu Expressway, Jungbu Expressway and Pangyo-Guri Expressway. The survey results were compared with the AASHTO performance criteria and several foreign field survey results. It was found from this study that the Korean CRCP generally met the AASHTO performance criteria and compares quite well with foreign CRCPs.
