OPTIMAL REHABILITATION FREQUENCIES FOR HIGHWAY PAVEMENTS

The maintenance and rehabilitation of existing, mature facilities are becoming increasingly important components of highway activity. Yet, although the planning, budgeting, evaluation, and management of maintenance and rehabilitation are different from corresponding actions for new construction, comparatively little work has been devoted to the development of planning and management tools intended specifically for repair programs. For a number of reasons, the optimization of maintenance and rehabilitation policy is difficult, and new concepts and analytic approaches need to be formulated to address this problem. Recently, the usefulness of dynamic control theory for optimizing transport investment decisions has been demonstrated. Control theory structures a problem in terms of a dynamic (i.e., time varying) objective function (e.g., maximize total transport-related benefits over time) subject to dynamic constraints (e.g., equations describing changes in pavement condition due to deterioration and repair or variations in traffic levels responding to current pavement condition). The several factors that influence the problem are structured in terms of state variables (over which decision makers have no control, such as traffic, weather, and soil) and control variables (over which decision makers exercise judgment, such as maintenance and rehabilitation policy). Dynamic control theory thus presents an attractive analytical tool for management of highway infrastructure; it encompasses all the key variables of interest, allows technically correct engineering and economic relationships to be expressed in problem formulation, and leads directly and efficiently to solution of optimal maintenance and rehabilitation policy. The tenets of dynamic control theory are described, and a numerical example of the use of dynamic control theory to optimize the overlay frequency on highway pavements in the United States is given.
