Abstract :
Heavy road vehicles are responsible for a significant portion of road damage, at a substantial financial burden to society at large. One of the most pressing questions that needs to be answered in the area of vehicle-generated road damage deals with the issue of spatial correlation properties of dynamic wheel loads produced by heavy road vehicles. This paper describes two types of instrumentation developed by NRC for its project to measure and analyze these properties. The paper deals with the general aspects of instrumentation used to measure vertical dynamic wheel loads at the interface of pavements and rolling tires, and with the design characteristics and performance of a high-precision odometer capable of measuring the distance travelled by a vehicle with a repeatability of ±2 cm over 750 m
