This report presents a review of the procedures developed in Texas for weighing trucks in motion. The Texas procedure features a portable strain gage scale installed in the pavement, with the electronic equipment used for analysis placed in a nearby van. Pavement roughness and the motion characteristics of vehicles are probably limiting factors that restrict the accuracy of any weigh-in-motion scale. However, these limitations do not appear to affect the usefulness of weighting-in-motion for pavement design purposes. It is essential to calibrate the weigh-in-motion equipment, using a truck of known platform weight, before each operation. The present procedures of obtaining static weights during the summer only may introduce substantially more error than the limitation of the weigh-in-motion equipment.
