Standard Specification for Smoothness of Pavement Profile at the Approaches to Weigh-in-Motion (WIM) Scales
standard by American Association of State and Highway Transportation Officials,

Description

Weigh-in-Motion (WIM) is the process of measuring the dynamic forces of moving vehicle tires on pavements and estimating the corresponding tire loads of the static vehicle. The dynamic forces of moving vehicles include the effects of road surface roughness and are modified by vehicle characteristics such as spring and un-spring mass, tire inflation pressures, out-of-round or dynamically unbalanced wheels and tires, suspension damping and the vehicles’ aerodynamic characteristics. The smoothness of the pavement surface at the approach to a WIM Scale directly affects the scale’s ability to accurately estimate static loads from measured dynamic forces. Lack of smoothness creates difficulties in calibrating WIM equipment and may cause poor results from subsequent vehicle weight data collection efforts.
