Pavement overload has become a significant concern in Indonesia due to its damaging effects on the pavement system, where most roads use flexible pavements. Meanwhile, overloading is also typical in other developing countries, causing everything from damage to accidents to the detriment of road users and operators. The current problem is that there is no definite knowledge of handling these overloaded vehicles, which has adverse effects. Therefore, this study aims to reveal the impact of losses caused by overloaded vehicles on flexible pavement. This research uses vehicle traffic load data to examine actual conditions in the field, which are converted to axle load values for each vehicle and used to determine pavement condition using the truck factor approach, mechanistic-empirical design, pavement smoothness level, and the impact of overloading due to fuel consumption by vehicles on flexible pavement. The results show that overloaded vehicles harm the flexible pavement. The increase in truck factor values for all vehicles in overloaded vehicles beyond the maximum allowable load results in more damage to the flexible pavement with an increase in truck factor values up to 83 %. The effect of overloading can be mitigated by increasing the thickness of the asphalt layer and the modulus of asphalt, so it is essential to pay attention to the quality of asphalt in anticipation of this overloading. To anticipate the overload phenomenon, it was found that the thickness of the asphalt overlay in the range of 170–205 mm could mitigate this detrimental effect. In addition, overloading affects the flexible pavement roughness and vehicle fuel consumption. Increased roughness and fuel consumption will increase road maintenance costs and affect driving comfort and safety. In addition, excessive fuel consumption can pollute the surrounding environment

The predominant type of pavement currently in use is flexible pavement constructed with a hot asphalt mixture. However, with economic development advancing in various regions, transportation challenges, such as vehicle overloading, especially in developing nations, have emerged. It is crucial to enhance and innovate the materials used in asphalt mixtures, which form the primary structure supporting pavement loads, to address these issues effectively. Incorporating green materials sourced from natural and waste sources becomes essential for promoting sustainable development. This study investigates the utilization of materials derived from the sap of the lannea coromandelica tree, known for its natural resin-like adhesives, as well as coal waste as a filler in asphalt mixtures. Laboratory experiments were conducted alongside vehicle load data analysis, focusing on excessive vehicle loads on roads. The findings indicate that incorporating these green materials enhances the modulus value of the asphalt mixture, particularly in the lannea coromandelica gum with fly ash (LCGFA) mixture, which amounted to 4161 Mpa, followed by the lannea coromandelica gum with bottom ash (LCGBA) mixture by 3729 Mpa, compared to the control mixture, hot mix asphalt concrete. Additionally, these results influence the Truck Factor value of vehicles. The higher the truck factor value, the impact on the pavement structure is due to the vehicle load transmitted through the vehicle axis, which is forwarded by the pavement to the subgrade. The adoption of LCGFA and LCGBA reduces the Truck Factor value from 5,386 to 4,980 under the LCGFA mix and 5,143 under the LCGBA mix, indicating decreased pavement damage caused by the wheel axles of overloaded vehicles. Consequently, utilizing these green materials is considered capable of providing enhanced durability and environmental benefits to pavement structures. In addition, this material can be used by field practitioners to reduce material costs and environmental impact.
