Presenting a Heuristic Method to Solve the Problems Relating To Road Maintenance and Rehabilitation

Roads are one of the most important assets in each country. Road network are too extensive and the budget needed for reconstruction is too high. To maintain these properties planning for the maintenance and rehabilitation is an important issue. Aging, traffic (especially trucks) and weather condition in the region cause numerous tensions in the pavement. These tensions are the main reason of distress, reducing ride quality and finally deterioration in the pavement. Because of the increasing rates of the costs associated with maintenance and repair there is a concern about keeping roads in good condition with the lowest costs. The main purpose of this research is to apply an evolutionary model to minimize the costs of maintenance and repair operation and at the same time maximizing the benefits of the system for a long time with acceptable service quality. The models are assessed on the hypothetical networks and the results have been satisfactory..
