Application of weigh-in-motion technologies for pavement and bridge response monitoring: State-of-the-art review

Abstract

Overweight vehicles may cause damage and premature deterioration of pavement and bridge structures. Weigh-in-Motion (WIM) is efficient in avoiding structural damage and ensuring successful weight enforcement by measuring a vehicle's weight in a dynamic state. WIM additionally provides information such as traffic volume, vehicle's speed, axle spacing, equivalent single axle load (ESAL), individual axle and gross vehicle weight (GVW), which is of value to planning, design, construction, and operations of transportation infrastructures. This paper reviewed the state of practice and research in WIM with focuses on its potential, limitations, cost-effectiveness, and data usage. Discussion was made on identifying needs and challenges for further development. This review provides the research community with a holistic view of available WIM techniques, their limitations, cost-effectiveness, and the need for future research on usage of the WIM data that might lead to wider adoption of WIM in transportation applications.
