Investigating the pavement efficiency of freight vehicles using weigh-in-motion systems
Weigh-in-motion (WIM) technologies allow the weight of individual vehicles and axles of trucks operating on roads to be measured without interfering with the flow of traffic. This paper introduces WIM systems and illustrates how WIM data can be used to investigate the effects of high productivity vehicles on road infrastructure. A comparison of the impacts of B-Doubles with semi-trailers on pavements operating in Melbourne is presented. The Pavement Wear Damage Factor (PWDF) is a main indicator used to represent the vehicle damage on pavement. It is found that although the average PWDF for B-Doubles was higher than that of semi-trailers, the average freight carried by B-Doubles was much heavier than semi-trailers. Also, the average PWDF for semi-trailers was larger and grew faster than that for B-Doubles when the payload was over 8 tonnes. The results indicate that B-Doubles provide a substantial increase in efficiency (higher loads with less pavement damage) at higher load levels.
