Abstract
Roads are a means of connecting one area to another that can be traversed by vehicles. The initial damage condition of the highway is mainly caused by the presence of overloaded cars passing through the road, poor planning of the quality of the dense traffic pavement layer that does not comply with the requirements, design errors in determining the thickness of the pavement, and inadequate road supporting facilities (road drainage system). To anticipate road damage, an overlay is needed. This research was conducted on the Lolowau-Siwalawa II road in Gunungsitoli City, along 10.7 km. The calculation of the overlay thickness was carried out using CESA analysis. The study's results indicated that the road pavement width was planned to be 4.5 meters, with two lanes and 2-way vehicle lane directions, and a design life of 10 years. Overlay with Lapen pavement of 22 cm and a cover layer of 7 cm.
