Abstract
This paper explains the analysis to calculate road pavement distress loss cost resulted from overloading and therefore the amount of loss cost the overload car users shall bear can be determined. Overloading heavy vehicle causes road pavement structural distress and service lifetime decreasing during design lifetime. The presence of overloading is indicated by the width area of rutting which is more than 60% of total road structural distress per km and by real maximum axle load (MAL) of the heavy vehicle which is larger than its standard MAL. The loss cost of road pavement distress due to overloading is calculated based on damage factor (DF) and deficit design life (DDL). The loss cost the overload car user shall bear is 60% of total DFC (damage factor cost) and DDLC (deficit design life cost), considering that not all pavement structural distresses are absolutely caused by overloading freight transport.
