COMBINED PRIORITY PROGRAMMING OF MAINTENANCE AND REHABILITATION FOR PAVEMENT NETWORKS

Total expenditures for maintenance and rehabilitation of a pavement network should represent an optimum combination of the two types of activities. Under the usual situation of budget constraints, this requires the establishing of priorities. An integrated method for programming maintenance and rehabilitation for paved road networks for any chosen program period is described. It begins with a common inventory of condition, serviceability, structural adequacy, traffic, unit costs, and other information. The maintenance programming subsystem evaluates alternative treatments for different types, densities, and severities of distresses and produces a demand-based budget by using a maximization of cost-effectiveness. The rehabilitation programming subsystem similarly evaluates alternatives, and a priority list of year-by-year projects over the program period, based on benefit maximization, is produced. The total of maintenance and rehabilitiation costs for any given year does not exceed the total budget limit. A case application is provided to illustrate the method. It uses the arterial street network of a small city, subdivided into 100 sections. The outputs include section-by-section, year-by-year, recommended programs of maintenance and rehabilitation work. An additional feature of the method is a capability for evaluating the long-term effect of various budget options on average network serviceability. Two rehabilitation budget levels, representing the expected funding and a zero budget, have been tested for the case application. As expected, average network serviceability was estimated to decrease significantly over the 10-year programming period for the zero budget case. Finally, it is recommended that year-by-year updates be carried out on the inventory and the maintenance and rehabilitation programs. (Author)
