ABSTRACT:
A road joint is disclosed formed by two rigid frames (4) joined together by a flexible strip (2) formed by an elastomer body having in cross section the form of an upside-down truncated V with thick legs and reinforced by a central horizontal rigid plate (1). The frames are disposed on opposing sides of the center of the joint and each include a lower horizontal heel (3) on which a corresponding leg of the elastomer body rests and is adhered. Rigid plate (1) includes two lateral members slanted slightly with respect to the horizontal and the heels of the frames (4) have upper surfaces (8) parallel to these lateral members. The slanted heels (3) of the rigid frames (4) orient the legs of the flexible strip (2) such that vertical deformation of the flexible strip (2) is minimized.
