The objective of this report is to conduct a review of the present and previously developed work devoted to the study of vehicle/road interaction. In particular, two of the most pressing questions that are to be answered in the area of heavy vehicle-generated road damage deal with the spatial repeatability of dynamic wheel loads produced by heavy road vehicles due to different types of suspension systems and the use of wide-base and dual tires. The outcome of this review, which is a part of the Federal Highway Administration Truck Pavement Interaction research program on truck size and weight, plays a determining role in assessing heavy truck suspension systems, tire configurations, and their contribution to pavement damage.

Vehicle dynamics and road dynamics are usually considered to be two largely independent subjects. In vehicle dynamics, road surface roughness is generally regarded as random excitation of the vehicle, while in road dynamics, the vehicle is generally regarded as a moving load acting on the pavement. This book suggests a new research concept to integrate the vehicle and the road system with the help of a tire model, and establishes a cross-subject research framework dubbed vehicle-pavement coupled system dynamics. In this context, the dynamics of the vehicle, road and the vehicle-road coupled system are investigated by means of theoretical analysis, numerical simulations and field tests. This book will be a valuable resource for university professors, graduate students and engineers majoring in automotive design, mechanical engineering, highway engineering and other related areas.
