Establishment of Performance Related Specifications Using Pay Factors and Relationship between Fatigue Cracking and Pay Factors

This study aims to address the development of performance based payment adjustment methods. First, this study describes the cases in which the pay adjustment has been applied and influential factors used in forty states of U.S. Based on those preliminary studies, it has been determined that the applicable factors that can be used for the pay adjustment of asphalt pavements in Korea. This study develops a more systematic and reliable algorithm that can be trusted by both builder and vendee. The percent within limit (PWL) has been analyzed as a rational estimation and measurement tool for asphalt pavements. The correlation between fatigue cracking and pay adjustment factors has also been investigated in this study. The fatigue life was increased or decreased due to changing asphalt content, density and gradation.
