Road Profile Information

Proposed Research Concepts and Stages

Proposed Research Concepts and Stages
  1. Road Profile Information - will provide the dynamic input from the road to the vehicle used in vehicle model analysis;
  2. Vehicle Model -to obtain parameters from the industry or by direct measurements, a computer model is used to assess dynamic loading;
  3. Pavement Model -to use existing pavement models based on fatigue or rutting to estimate the road damage due to heavy vehicles;
  4. Verification -to set up an experiment to verify the damage model; and
  5. Permit Policy -to obtain permit policies based on the research
