Abstract

The growing needs for accessibility within the UBT campus area, along with the increasing number of academic community and the use of private vehicles, underscores the urgent need for an integrative internal road network to facilitate inter-zone mobility. This study aims to determine an alternative flexible pavement thickness using the MDP 2024, which adopts a mechanistic-empirical framework. This method is chosen for its ability to accommodate actual traffic conditions and local subgrade characteristics, particularly in areas with low traffic volumes. The research is based on secondary data from the report of the Detailed Engineering Design 2019 and traffic survey at 2025, which revealed the absence of commercial vehicles, classifying the road as a local access route. Consequently, the design traffic load was set at 0.5 x 10⁶ CESA4. The subgrade’s CBR value of 6% indicates a normal soil base condition. The pavement structure was selected based on Design Chart-4, resulting in a composition of 30 mm HRS-WC, 35 mm HRS-Base, 250 mm Class A Aggregate Base, 150 mm Class B Aggregate Subbase, and 400 mm of selected fill. These findings suggest that the application of MDP 2024 enables pavement structure planning that is responsive to actual traffic loads and geotechnical conditions in educational areas with low-volume traffic, while also offering potential benefits in material efficiency and ease of implementation.
