ABSTRACT
The Virginia Department of Transportation (VDOT) uses the results of automated video distress surveys to assist in developing maintenance priorities to manage the pavement on Virginia’s interstate and primary roadways. Totaling nearly 43,200 lane-km (27,000 lane-miles), these roadways consist of flexible, rigid, and composite (flexible over rigid) pavements. The video-based surface distress data consist of quantities of distress that are visually observable at the pavement surface; however, no information regarding the structural capacity of the pavement system on a network level is currently available. The distress quantities are then transformed into a condition index. Along with the condition index, individual distress quantities and severities are used to determine typical maintenance treatments and associated costs are calculated. It is from this process that an unconstrained performance-based maintenance budget is developed.
