Expansion joint specifically designed for highway use within structures creating longitudinal movements of ± 15 (mm), vertical movements up to 10mm. It consists of an extruded rubber bellows, vulcanized to two 80x80x9 mm T-profiles and anchored to the slab by clamps of suitable diameter, placed at a centre distance of 240 mm. The extruded rubber, together with the steel profiles it is vulcanized to, makes up a water-tight system and seamlessly covers the entire width of the road bed. Water-tight capacity around the areas close to the joint is ensured by appropriate water-proof materials. POS.
