The need to provide enhanced performance of both heavy freight vehicles and road infrastructure through appropriate management has been recognized at policy level. This report, prepared by an OECD group of experts, provides a scientific review of the causes and effects of vehicle wheel loads on pavements and bridges highlighting the importance of dynamic impacts of heavy vehicles. Current and future vehicle and suspension design and its effect on dynamic pavement loading are assessed. The OECD Group recommends ways of implementing scientific knowledge to improve productivity and reduce road costs and identifies research needs to promote the use of "road friendly" vehicles.
