To improve the understanding of the nature of dynamic wheel loads and associated pavement damage, Austroads commissioned ARRB Group to research heavy vehicle dynamic wheel loads through the development and implementation of a measurement system as a means of providing important performance data. The objective of this project was to improve knowledge and understanding of the in-service dynamic wheel loads and load-sharing characteristics of axle groups through the development of a measurement tool.
