Abstract
The various conditions of dynamic vehicle tire forces on pavement loading have been investigated by using strip type commercially available piezo-electric Weigh-In-Motion (WIM) sensors. Usually, the WIM load is found by empirically relating the peak voltage of the signal to the static wheel weight, and the area under the signal and the vehicle speed are not considered. A formula considering the area under the WIM signal and the moving load is presented. Whether or not static calibration factor of strip type sensors is sufficient to calculate the vehicle dynamic load is determined and a quasi-static vehicle pass over calibration methodology for future experiments is suggested. This paper also reviews the detailed description of the research carried out on existing WIM sensors and related systems.
