Abstract
Concrete pavements are exposed to high loads from existing traffic volumes and extreme weather conditions. In order to prevent wild cracking caused by the resulting constraining stresses, transverse joints are usually installed. However, these are also weak points in the concrete pavement, so that continuous maintenance and upkeeping is necessary. An ecologically and economically viable alternative to renewing the entire concrete slab is to rehabilitate the concrete runway with the aid of a jointless as well as thin top layer of carbon reinforced concrete. By separating the bond between the old concrete layer and the carbon concrete layer in the area of the transverse joint, a distribution of cracks is ensured and the crack width of the individual cracks in the carbon reinforced concrete pavement is reduced by multiple crack formation. Liquids can therefore penetrate less deeply into the concrete and damage neither the old concrete layer nor the corrosion-resistant carbon reinforcement.
