Rigid pavement optimization by using empirical mechanistic method and Kenpave software

Abstract

This research was undertaken on TNC Main Road to CBD project with the aim to find an optimum design, by using Manual Perkerasan Jalan 2017 and Kenpave software. The existing pavement was redesigned to achieve a design life of 40 years, instead of 20 years. The design was also compared with other alternative designs that were obtained from past research study. The analysis was done by comparing the maximum stress values, maximum deflection values, and material cost per meter. It can be concluded for this study that the pavement modification using slag aggregates in concrete mixture as the surface layer was the most optimum pavement design as it has the lowest maximum stress and deflection values, and thus lowest cracking index and longer designed life, with a reasonable construction material cost.
