69 International Road Dynamics (IRD) has been awarded a $4.9m contract to help manage the Federal Highway Administration (FHWA)’s weigh-in-motion (WIM) programme. IRD’s role over the five-year deal is to install and maintain the WIM systems at Long-Term Pavement Performance test sites - and verify that the data collected from them conforms to various specifications. The FHWA’s Office of Infrastructure Research & Development needs the data to understand how various pavement types perform as they do. The information has been collected across North America since 1989.
