Budgets for all forms of airfield construction, including maintenance and rehabilitation, continue to dwindle. With this decrease, the importance of managing existing pavement assets becomes increasingly significant. Airport managers often tend to delay pavement maintenance and rehabilitation without analyzing, or sometimes realizing, the effects of such decisions on future maintenance and rehabilitation costs. One of the most important steps to overcoming this potential problem is the emplacement of an effective pavement management system (PMS). A pavement management system is defined as a set of tools or methods that can assist decision-makers in finding cost effective strategies for providing, evaluating and maintaining pavements in a serviceable condition. A quality pavement management system provides critical information required for airport managers to properly analyze the structures under their purview. From this analysis, the airport manager can determine maintenance and rehabilitation requirements, project priorities, and can conduct more efficient long-term planning. |
