ESTIMATION OF NETWORK REHABILITATION AND MAINTENANCE COSTS OVER AN EXTENDED PLANNING HORIZON (ABRIDGMENT)

RENU is a computerized procedure to estimate funding levels required for rehabilitation, preventive maintenance, and routine maintenance of a highway network. The overall highway network consists of one or more pavement systems and each system may include several types of pavements. RENU can also be used to estimate the cost impact of changes in the legal axle load limits. The model uses a serviceability and distress approach to determine the timing for rehabilitation. Performance, distress, and survivor curves are generated based on pavement data collected from the Texas pavement system. RENU has the capability of generating survivor curves or different desired performance levels; it also contains the options of multiple overlays and the addition of new mileage during the planning horizon. A particularly interesting feature of thee program is the estimation of rehabilitation costs associated with the upgrading of all pavements already in critical condition at the beginning of the analysis period. In addition to these costs, RENU also estimates the costs of keeping the network at a desired performance level during a specified planning horizon.
