Overloaded vehicles damages roads and road structures such as bridges and destroys the country's high-cost road network, which is built at a high cost. Overloading more than the standard capacity of vehicles is one of the effective factors in damaging the roads. In general, the phenomenon of overloading of freight vehicles is common in developing countries where traffic control measures are poorly implemented. On the roads of the country, according to the studies, it is predicted that on average, at least “between” 5% to 10% of the trucks have overload conditions. This is one of the most important factors in reducing the service life of road pavement. In this paper, the results of data analysis collected from the weigh-in-motion system (WIM) and the effect of overloaded vehicle on flexible pavement are presented. By calculating the equivalent axial loads and damage factor (DF) to the road pavement, the remaining service life (RSL) of the pavement has been determined by considering Overloaded truck impact. The analysis showed that the damage factor obtained from WIM information is to the extent that it reduces the service life of the pavement.
