Development of Pavement Deterioration Model for Rigid Pavement (Case Study: Cikopo-Palimanan Toll Road)

Abstract

Pavement deterioration will bring disruption to traffic, and it is hoped that the pavement is always on an acceptable condition. If the pavement distresses could be predicted correctly when the repair and maintenance plan was designed, the distresses could be addressed, and preventive steps can be taken to minimize the damage that will occur. This study aims to develop a mathematical model to predict pavement condition, which was represented by using International Roughness Index (IRI) value, for some sections constructed with rigid pavement at Cikopo-Palimanan Toll Road. In this study, there were several parameters that were analysed, including pavement age, traffic volume, and heavy commercial vehicle (HCV), to determine which parameter(s) affect the IRI value. It was found that pavement age has the most significant effect on IRI value. Moreover, a pavement deterioration model that considers pavement age, traffic volume and HCV has been developed.
