Impacts from truck traffic on road infrastructure

Economic constraints nowadays require transporting greater volumes of freight at lower cost. Yet, physical profiles of trucks do not all generate the same effects on road infrastructure for a given tonnage hauled. The objective then lies in finding an optimal service level that reduces the damage (wear) caused to infrastructure (Jacob, 2013). Results derived for the impact of trucks on pavements relate specifically to rutting as well as the potential for evaluating the aggressiveness with which axle configurations induce fatigue on asphalt pavements. The impact of truck traffic trends on road bridges will also be discussed herein.
