Traffic load has a significant impact on the rate of pavement construction degradation. Therefore, when designing pavement construction, in addition to data on the number of vehicles, knowledge of their weights or axle loads is necessary. By analyzing the traffic load, the number of equivalent axes expressing the design traffic load is determined. The procedure for analyzing traffic load for asphalt pavements in the Republic of Croatia is conducted according to the standard HRN U.C4.010. Analyzing the impact of vehicle overloading on the lifespan of pavement construction is an important aspect of study to ensure the safety and durability of roads. Vehicle overloading refers to the situation when a vehicle exceeds the permissible road load capacity, which can cause damage to the pavement. Key factors to consider in the analysis of the impact of vehicle overloading on the lifespan of pavement construction include: pavement capacity, materials used in pavement construction, deformations and cracks, routine maintenance, frequency of overloading, and regulations. In order to reduce the impact of vehicle overloading on the lifespan of pavement construction, it is important to systematically monitor the condition of roads, educate drivers about the importance of adhering to load capacity limits, and invest in regular maintenance and infrastructure renewal. This will contribute to increasing traffic safety and extending the lifespan of road surfaces.
