A METHOD FOR INTEGRATED PRIORITY PROGRAMMING AND BUDGET LEVEL ANALYSIS FOR PAVEMENT MAINTENANCE AND REHABILITATION --PROCEEDINGS OF THE FIFTH INTERNATIONAL CONFERENCE ON THE STRUCTURAL DESIGN OF ASPHALT PAVEMENTS HELD DEFLT UNIVERSITY OF TECHNOLOGY, AUGUST 23-26 1982. VOL 1 AND 2. -- NETHERLANDS

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 priorities to be established. This paper describes an integrated method for programming maintenance and rehabilitation for paved road networks for any chosen program period. 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, density and severity of distresses and produces a demand-based budget 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 rehabilitation 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 of average network serviceability. The rehabilitation budget levels, one representing the expected funding and one being 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.(a) for the covering abstract of the conference see IRRD 815640.
