Abstract: Road transport infrastructures are naturally exposed to several degradation factors. Traffic load (weight) and weather conditions represent two major causes of degradation which in turns result to demurrage an aftermath of delay. Asphalt rutting, bridge cracking, potholes, drainage system obstruction are all examples of weather induced degradation. Asphalt rutting for instance is induced by high temperature, but the effect is enhanced under high truck traffic axle load. Weather-related events such as (rainfall, blizzards, flood, sheet, snow and ice) are significant disruptors of travel time and other transport related operations.
