Abstract
Concrete surfaces in industrial areas, parking lots, roads, and motorways are typically provided with joints to prevent uncontrolled cracking due to stress gradients and restrained deformations. Thermal or hygric deformations are concentrated at these joints. To prevent the ingress of harmful substances into the concrete and its substrate, the joints are usually sealed with flexible polymer sealants. However, the durability of these sealing systems is limited despite regular maintenance. Moreover, the concrete in joint areas often exhibits premature damage caused by the combined effects of mechanical loading and environmental exposure. This article presents an alternative concept in which existing joints are covered with thin overlays made of carbon-reinforced concrete (CRC). These CRC layers enable the transformation of local joint openings into quasi-ductile deformations by multiple fine cracks within a predefined area, thereby extending the service life of the concrete pavement. Firstly, the study investigates the load-bearing and deformation behavior of the CRC overlays under biaxial tensile loading at various load ratios. Secondly, the bond properties between the CRC layer and the underlying concrete, as well as the ductility and cracking behavior under quasi-static uniaxial tensile loading are examined using large-scale specimens.
