CA 2566889

A pavement joint (101, 102) disposed between two contiguous pavement slabs (103, 104 and 105) incorporating a shear key (12, 13, 22 and 23) and at least one hinge (37, 38, 39 and 40). The shear key and the at least one hinge are operative when at least one of the slabs is subjected to out-of-plane action P with the shear key transferring shear between the slabs, and the at least one hinge accommodating angular displacement of the slabs relative to the joint axis in at least one direction. In one form, a joint member (20) is disposed between the slabs to provide the shear key and hinge. A joint member and pavement slab for use in the joint is also described.

Cette clé de cisaillement et cette articulation sont opérationnels lorsqu'au moins une des bordures est soumise à un effort P en dehors du plan, la clé de cisaillement transférant le cisaillement entre les bordures et l'articulation permettant un déplacement angulaire des bordures par rapport à l'axe du joint dans au moins une direction. Dans une forme de réalisation, un joint (20) est placé entre les bordures de façon à fournir une clé de cisaillement et une articulation.
