Handbok – Drift, underhåll och reparation av betongvägar

Bengt-Åke Hultqvist

The Swedish concrete road network today consists of 68 kilometer of motorways built in the 1990’s and 2000’s. The concrete roads were designed and constructed to have a long life and have mainly performed well requiring little maintenance or additional expenditure. As the concrete roads get older, different kinds of damages start to form. In this report, a set of examples are given that describe the different kinds of damages and possible causes. Furthermore, possible maintenance methods are suggested. Damages such as cracks and slab stepping in joints are starting to form in some of the older concrete roads in Sweden. A few concrete roads have rut formations due to wear from studded tyres. Damage types and maintenance methods often differ for concrete roads compared to asphalt roads. It is therefore important to spread the knowledge of damage types and maintenance methods for concrete roads. One of the most important issues is to make sure that joints and cracks are sealed as soon as possible. By regularly inspecting the concrete road and carrying out necessary maintenance, the foundation for a long life is laid. A well-built and well-managed concrete road should be possible to use for 40 years without the need for any larger repair measures. A prerequisite to being able to choose the right maintenance methods is to know the cause of the damage. The cause of damage should always be determined by investigations that can be more or less extensive. Different kinds of damages have been compiled into a catalogue. Maintenance and rehabilitation methods are described in their own chapters.
