Available funds are, typically, not adequate to satisfy all the required maintenance projects for highways and roads networks in most countries, including Egypt. Under current policies and funding levels, further deterioration in pavement conditions can be expected, since the budget needed for highway maintenance is greater that the funding levels available. As a result, highway agencies must seek more cost-effective methods for highway network preservation. The development of pavement management optimization model is essential to manage maintenance of highways and roads networks in Egypt. In this paper, a Pavement Maintenance Management Optimization Model (PMMOM) for highways in Egypt is developed using genetic algorithms optimization application, designed as an add-in for MS Excel™. Markov chain theory is used to generate the Transition Probability Matrices (TPM) for each type of maintenance activities. The models used in PMMOM are developed using the available data at the General Authority for Road Bridges and Land Transport (GARBLT) in Egypt for two major highways, which are Cairo-Alexandria agricultural highway and Alexandria-Matrouh north coast highway, representing the agricultural roads and coastal roads conditions in Egypt, respectively. PMMOM was developed for a planning horizon of 10 years. Seven optimization budget and performance constraint scenarios were demonstrated in this paper. The results show that the model is sensitive enough to reflect the differences of optimization analysis constraints on the analysis results, and can provide an effective tool for planning maintenance activities under different budget and/or performance optimization constraints.
