Abstract

Hangtua Road in Palu City serves as a vital connector between the Talise and Tondo sub-districts, providing access to educational institutions, commercial areas, and residential zones. The road segment has shown visible structural damage at several points, raising concerns about its serviceability under increasing traffic demand. The problem addressed in this study is the decline in pavement performance, which threatens road safety and accessibility. The objective is to evaluate the stress and strain levels of the pavement, estimate its remaining service life, and propose appropriate maintenance solutions. A descriptive research method was employed, supported by field investigations. Primary data were collected from the Benkelman Beam (BB) deflection test and the Dynamic Cone Penetrometer (DCP) test for CBR values. The maximum deflection recorded was 0.325 mm at STA 0+500, while the minimum was 0.168 mm at STA 0+700. The analysis indicates that the existing pavement structure can continue to serve adequately if supported by routine maintenance. The recommended solution is the application of a non-structural overlay, which is expected to extend the pavement's service life by approximately 10 years while accommodating projected traffic growth. These findings provide practical guidance for local road authorities in planning cost-effective and sustainable maintenance strategies.

Abstract

Flexible pavements on highways often experience damage due to increased traffic volume and load, which impacts the service life and road maintenance costs. This study aims to evaluate the effectiveness of the 2024 Road Pavement Design Manual and CIRCLY 7.0 software in analyzing performance and predicting the remaining life of flexible pavements. The research method uses a quantitative approach with data in the form of Average Daily Traffic, road design age, vehicle growth rate, and load equivalent factor. The evaluation is carried out through manual calculations based on MDPJ 2024, including cumulative traffic load estimation  and subgrade CBR analysis values, then modeled using CIRCLY 7.0 for pavement structure simulation. The analysis results show that the existing pavement thickness does not meet the MDPJ 2024 requirements with a CESA value of 0.916×10⁶ for a design life of 20 years. Based on MDPJ 2024, the recommended pavement thickness is 875 mm, while the results of the CIRCLY 7.0 analysis show that a thickness of 350 mm is still suitable for light to medium traffic..
