The Evaluation and Calculation of Hotmix Pavement Thickness at Dolok Sanggul Silimbat Road Section in North Tapanuli Districts

Abstract

Road is a land transportation infrastructure which is very important to support development activities and accelerate regional development in an effort to achieve the level of prosperity and welfare of the people. This study aims to analyze the thickness of the pavement layer of the hot mix road in the field and to compare the results of the calculation evaluation using component method analysis. The research method in this study uses the analysis of planning calculations with the Component Analysis Method based on the Flexible Pavement Thickness Planning Guidelines Pt T-01- 2002-B which refers to the AASHTO Guide design of pavements structures in 1993. Based on the calculation results obtained in the component method shows the pavement thickness value. path a1 = 13.5 cm, a2 = 15 cm, and a3 = 10 cm. The pavement thickness value in the field is greater than the pavement thickness value in the calculation results. This is due to environmental adjustment factors because it has areas with high rainfall so that the economic life of the road is planned to be achieved Determination of road pavement calculations, especially in determining the number of LHR where the road is a district road that is rarely traversed by heavy vehicles, then the determining factor for heavy vehicles assumed vehicle.
