Abstract

The background of the study is the increasing traffic load, especially heavy vehicles, which has exceeded the initial design capacity of the road, causing premature damage. Data collection includes traffic volume surveys, CBR tests for subgrade bearing capacity, and deflection measurements. The 2017 MDP method is used to determine the overlay thickness and the need for road widening. This study analyzes the overlay thickness requirements on the Tolai-Sausu National Road section in Central Sulawesi Province using the 2017 Pavement Design Manual (MDP) method. The results show that the existing pavement structure on the Tolai-Sausu National Road section is no longer able to withstand the planned traffic load, so additional overlays with varying thicknesses are needed in several segments. The 2017 Pavement Design Manual method recommends a thickness ranging from 4 cm as the minimum thickness for light to moderate damage, and 12.5 cm as the maximum thickness for severe damage, so the design is adjusted to the level of damage and the structural capacity of the road. Although it has an impact on increasing construction costs, it is able to provide a long-term solution.
