Technology Can Signal Road Repair Needs (original) (raw)

2001

Abstract

New technologies that allow comprehensive, high-speed pavement inspections also require agencies to make institutional adjustments in order to take full advantage of them. Agencies should change ratings systems to use the new 3-D capabilities, rather than continuing to rely on generically indexed values. Predictions about future decay can be more precise, which means managers will have to un-learn the tendency to over-compensate for uncertainty by repairing pavement before it needs to be fixed. Agencies can use the new information to develop maintenance scheduling models that incorporate new data and improve themselves over time. Managers and inspectors will need to acquire new skills to master these new techniques.
