Evaluation of Pavement Structure and Cost Based on the Road Pavement Design Manual and Component Analysis Method

In transportation systems, two main elements are closely related: traffic and pavement. Pavement is a part of road construction designed with specific layers, thickness, strength, and stability to safely distribute vehicle loads to the subgrade. This study aims to determine the required pavement thickness for the Adam Malik Road using the Pavement Design Manual (MDP) 2017, MDP 2024, and the Component Analysis Method, as well as to compare the cost estimates (RAB) of flexible pavement obtained from these three approaches in order to evaluate their efficiency, accuracy, and relevance to project conditions. The analysis results indicate new pavement structure configurations for Adam Malik Road. Using MDP 2017, the structure consists of a 4 cm Wearing Course (AC-WC), a 6 cm Binder Course (AC-BC), and a 40 cm Upper Base Course (LPA). MDP 2024 produces a 6 cm Wearing Course (AC-WC), a 20 cm Upper Base Course (LPA), and a 15 cm Lower Base Course (LPB). Meanwhile, the Component Analysis Method results in a 5 cm Wearing Course (AC-WC), a 15 cm Upper Base Course (LPA), and a 15 cm Lower Base Course (LPB). In terms of cost, the AC-WC layer using MDP 2017 yields an estimated cost of Rp 7,739,010,060, MDP 2024 yields Rp 6,270,761,799, and the Component Analysis Method yields Rp 5,708,044,446. The lowest cost is obtained from the Component Analysis Method, which produces the thinnest pavement thickness compared to MDP 2017 and MDP 2024.
