• Abstract:
  Evaluation of pavement structural capacity and integrity is an important component of the Pavement Management ; System (PMS) to assist in the selection of suitable maintenance and rehabilitation strategies. The falling weight ; defl ectometer (FWD) is a non-destructive defl ection testing method that is widely used at the project-level to assess ; the structural capacity of in-service pavements. However, issues such as expenses involved in data collection and ; scarcity of resources appear to present obstacles for a wide adoption of FWD for pavement testing at the network ; level. In addition, delays due to lane closures may compromise the safety of the traveling public and highway ; workers, which may not justify the worth of the collected data. The rolling wheel defl ectometer (RWD), which ; measures defl ections at highway speeds, was introduced to support existing non-destructive testing techniques by ; providing for a screening tool of structurally defi cient pavements at the network level. RWD testing does not cause ; traffi c disruption or decreased safety along the tested highway. This nondestructive testing (NDT) device also off ers ; the potential of characterizing the structural capacity and integrity of the pavement network in an eff ective way in ; terms of time and cost associated with the testing process.
