Expansion joints made of asphalt serve to absorb the movement of structures without damage at crossings to the road. They also prevent water from penetrating the substructure. Its functionality is based on the interaction of a special, permanently elastic impregnation material made of polymer-bitumen and a stable aggregate matrix. Proper execution requires both the highest precision and extensive expertise and is subject to strict technical specifications.
