Performance Evaluation of JPCP with Changes of Pavement Mix Design Using Pavement Management Data

This study aimed to analyze long-term performance of JPCP (jointed plain concrete pavement) according to changes in standard mix design using evaluation of concrete properties based on Korea HPMS (highway pavement management system) and Korea LTPP (long-term pavement performance) data accumulated for over 15 years. The concrete pavements built in the 2010s by the specification of a durability-based mix design adopted in 2010 were found to have better performance with much fewer surface distresses than the concrete pavements built before 2010 by the specification of a classical strength-based mix design. Also, in order to realize long-life concrete pavement, experimental construction was carried out for high-durability concrete mix design. The performance monitoring data for the construction site implied that the high-durability mix design can make it possible to lead a long-life concrete pavement.
