The objective of this paper is to describe an investigation by the Washington State Department of Highways to determine the feasibility of developing a pavement management system. A pavement management system, as envisioned by this investigation, should provide systematic and reasonably objective information regarding the optimum economic maintenance strategy on a project-by-project basis. The system is concerned primarily with the development of a performance prediction model and a cost model, both to be based on the data bank of information that has been collected by Washignton during the past 6 to 8 years. This paper describes two approaches to the performance model: a regression equation and a probability transition matrix. Efforts to develop a prediction model by regression techniques were unsuccessful. The transition matrix appears promising and relatively simple. General procedures for development and use of this model are given in the paper. A cost model is developed that includes considerations of routine maintenance costs, construction costs, interest, inflation, and excess user costs. The pavement management system framework as developed provides an objective procedure for comparing the performance and cost models of several maintenance strategies and selecting the strategy that will be the most economical for any designated time period. /Author/
