Analysis of Rigid Pavement Reconstruction Using The 2024 Bina Marga MDPJ Method And Implementation Method on The Surabaya-Gempol STA Toll Road Section 10+200 – 11+400

Abstract

Rigid pavement is widely implemented on toll roads due to its high structural capacity to withstand heavy traffic loads and its long service life. This study aims to determine the required rigid pavement thickness for reconstruction based on the 2024 Bina Marga Pavement Design Manual (MDPJ) and to evaluate its construction implementation on the Surabaya–Gempol Toll Road, specifically between STA 10+200 and STA 11+400. A quantitative research approach was employed using literature review and secondary data analysis, including Average Daily Traffic (ADT), subgrade California Bearing Ratio (CBR), and geometric road characteristics. The pavement design analysis was carried out in accordance with the procedures specified in the 2024 MDPJ Bina Marga. The results indicate that the cumulative number of commercial vehicle axle groups (JSKN) over a 40-year design period reaches 41,791,131.23, while the equivalent subgrade CBR value is 20.04%. Based on these parameters, the proposed rigid pavement structure consists of a 300 mm Portland cement concrete slab, a 100 mm lean concrete base layer, a 200 mm Class A aggregate base course, and a 200 mm selected granular subbase layer. Structural performance evaluation shows a fatigue damage value of 0.00% and an erosion damage value of 82.51%, both satisfying the allowable design criteria. Therefore, the proposed pavement structure is considered structurally adequate, technically feasible, and capable of providing reliable long-term performance throughout its planned service life.
