The bridge management of a toll motorway network results of current developments and implementations

Abertis-Autopistas-España operates a highway network that is nearly 1500 km long. A “new generation” Bridge Management System centrally based and operated is being used for the management of the 3427 bridges of the road network. This paper presents some results of the implementation of the system, mainly concerning the most frequent damages observed on the inspected bridges, depending on the type and location of each bridge, the degree of inspection and maintenance and the amount of traffic. The Bridge Management System implemented by Abertis-Autopistas-España is able to make an estimation of the expected cost for repairing the damages reported by the Principal Inspections considering the main properties of the observed damages, their location and the access of the damaged elements. Additionally, a priority ranking can be calculated. This paper also includes the results of the implementation of these criteria to the mentioned 3427 bridges and the improvements that Abertis-Autopistas-España has gotten when using the Bridge Management System. As a result of the implementation of the system, some relevant damages produced mainly because of the usage of chlorides in winter time on certain bridges were found. Finally, some of the proposed rehabilitation works made for correcting the said problems are also presented on this paper.
