Remedial measures works programme for Slovenian motorway infrastructure

Abstract

The motorway infrastructure consists of pavements, bridges, tunnels, noise barriers, drainage systems, electro‐mechanical equipment and road furniture. All of them need to be at the adequate performance levels to ensure appropriate availability, comfort and safety. To fulfill this condition, road authorities must regularly carry out maintenance, rehabilitation and reconstruction works. As engineering structures have various service lives, performing remedial works for each individual structure at the optimal time would result in frequent road closures on the same road sections, significantly reducing the road availability for the users. Consequently, a works programme of remedial measures is needed which combines the measures on the same road section to the same time frame. The times planned for performing remedial measures therefore cannot be optimal for every structure in the road network, however they can be optimal from the road's availability and total costs perspective. An appropriate coordination between individual types of infrastructure, selection of measures and a method of merging these measures to the individual road sections must be performed. The paper discusses the integration of the results of individual management systems into a unified works programme.
