Abstract
The increasing number of overloaded freight vehicles has become one of the major factors accelerating pavement deterioration on national roads in Indonesia. This study aims to analyze the impact of overloaded Colt Diesel Double (CDD) trucks on the service life of flexible pavement along Jalan Kartini (Bypass Klaten). The analysis was conducted using the American Association of State Highway and Transportation Officials (AASHTO) 1993 pavement design method. Data used in this study included pavement structure data, traffic volume data, road condition data, and vehicle weighing data collected from July to September 2025. A total of 127 CDD trucks were sampled using a simple random sampling method. The results showed that 85% of the observed vehicles were operating with loads exceeding the legal limit. The Vehicle Damage Factor (VDF) increased significantly from 0.266 under normal loading conditions to 3.12 under overloaded conditions, indicating that overloaded vehicles generate pavement damage approximately 11.7 times greater than normal vehicles. Furthermore, the annual Equivalent Single Axle Load (ESAL) increased from 82,750 ESA/year under normal conditions to 970,258 ESA/year under overloaded conditions. Based on the AASHTO 1993 analysis, the effective pavement service life decreased from the planned design life of 20 years to approximately 17 years, resulting in a service life reduction of 3 years. These findings demonstrate that overloaded freight transportation significantly contributes to the accelerated structural deterioration of road pavements and highlights the importance of stricter load control and road maintenance policies.
