Abstract: The device for the interconnection of two roadway parts (1a, 1b) separated by an expansion joint (3) consists of a plurality of joint strips (2) arrnaged end to end and in which each joint strip (2) comprises at least one deformable zone (4) extending parallel to the joint (3), between two fastening elements (5a and 5b) connected to the two roadways parts (1a, 1b), respectively. The deformable zone (4) consists of alternating deformable carrying elements (6) and bellows (7). Two undeformable carrying elements (18) belonging to the fastening elements (5a, 5b), respectively, are situated on either side of each bellows (7). Each of the deformable carrying elements (6) has a horizontal metal plate situated in the upper part of the joint strip (2) and carried by two elastomer blocks which are deformable by horizontal shearing and arranged symmetrically relative to a vertical plane parallel to the joint (3). Each of the bellows (6) consists of an elastomeric, continuous, relatively thin and non-plane wall.
