ABSTRACT
Most Pavement Management Systems (PMS) are not taking into consideration that a road network is a coherent system of road sections with a finite capacity. Pavement management of German motorways is undertaken by the road authorities of the federal states. The federal minister of transport always has a strong interest to minimize the negative economic effects by pavement maintenance. Therefore, the federal ministry is accepting higher roadworks costs if in turn lower societal costs will occur. In the case of pavement maintenance on the A9 motorway, the road authority of Saxony-Anhalt ignored the traffic effects and wider economic effects caused by their insufficient planning and organization measures for the pavement construction site. The pavement maintenance strategy follows traditional patterns by focusing on the objective to optimize the working conditions for the road construction company. With the conduction of a cost-benefit analysis, it is possible to calculate the additional internal and external costs that are caused by the pavement maintenance management that is disregarding the traffic effects of road networks. Furthermore, it is possible to calculate the related macro-economic effects by an inefficient pavement maintenance management system.
