Abstract
The joint is installed between two sections of roadway respectively supported by two contiguous structural elements. A driving surface is formed by a surface covering applied on top of the elements and interrupted above the gap separating them to form a trench. A closure member is placed in the base of the trench covering the gap, after which granulates and a binder which form a flexible material on curing are poured in. Before pouring in the granulates and binder, reinforcements are laid in the trench which are attached to the two structural elements at either end of the closure member. These reinforcements are perforated to allow the granulates to pass through. They therefore provide reinforcement for the joint in areas where there is a risk of tearing due to traction forces which tend to move the elements apart.
