Advanced Management Strategies for Road Asset Management
The management methods for maintaining road infrastructure have ever been subject to constant change: At first, these methods were only used for condition surveys and asset valuation of road infrastructure. Later, sophisticated developments of various computer applications were used not only to calculate financial needs, but also condition scenarios. Worldwide, all municipalities together have the largest road lengths and require asset management strategies in particular for their heterogeneous networks to maintain their road assets efficiently and economically. Today it is mandatory, in addition to the technical aspects of the condition survey and assessment of road surface and road substance, to gather detailed information about lifetime, life cycle considerations and financial ratios. Economic indicators are supplied by a future-orientated asset management making the sustainability of the maintenance efforts measurable. The road maintenance has to ensure not only an economic use of resources, but also the maximum benefit for the road users and the long-term preservation of the financial value of the road assets. The permanent availability at a safe level is a key performance indicator for road networks and a measure of the quality of these networks. Variational calculations can show the road condition development depending on the invested financial funds. With the help of these scenarios it is easy to detect if the asset values will be preserved in the future or there will be a loss in the assets. Detailed life cycle considerations are used for the analysis of different maintenance strategies. With a break down maintenance strategy the status and comfort level is at its lowest, because only already incurred damage will be locally repaired. With a preventive maintenance strategy in the sense of a prevention or minimization of damage and restrictions in the availability maintenance measures are carried out in timely fixed intervals. Final aim of a predictive maintenance strategy is the continuous, uninterrupted availability of the road network. With this strategy, maintenance works with a fixed and reliable lifetime have to be carried out at the optimum time. The choice of the maintenance strategy has a direct influence on the financial needs for the maintenance of roads and the availability of the network to its users. Therefore, advanced management strategies for road asset management are vital to preserve the asset values and assure safe and reliable road networks for passenger and freight transport at all times.
