Abstract

This paper objective is to mitigate to what extent the Liddle empirical formula (which the initial power equation of 4th order) may suit in designing road pavement lifespan for overloading vehicle roads. A case study was conducted in the Meredan highway, Siak, Riau, Indonesia. It was identified that the Truck Factor (TF) > 1 in this road. During 3 years project operation, the pavement condition has been deteriorated (Road Surface Index fail, IPf=1.5). Hence, the road was proven to be a failure before reaching its designated project lifespan (10 years). This study conducted various calculations by adjusting the Liddle empirical exponential formula (from power equation of 4th to 6th order) in order to fulfill the pavement lifespan which was capable to serve the overloading traffic loads in this road. This research has identified that there is a need to adjust the Liddle empirical formula by power equation of 6th order to accommodate the current overloading vehicles
