The invention concerns a joint set between two road sections respectively supported by two adjacent structural elements (1). A running surface is formed by a surfacing coat (2) deposited on the elements and interrupted above the space which separates them to form a trench. A sealing element (4) is placed at the bottom of the trench covering the space, then aggregates and a binder are poured in forming a soft material (3) after setting. Before the aggregates and the binder are poured in, reinforcing elements are set in the trench which are fixed to the two structural elements on either side of the sealing element. Said reinforcing elements are open-worked to allow the aggregates to pass through. Thus they enable to reinforce the joints in the zones where it is likely to be pulled by the tensile force tending to cause the elements to be spaced apart.
Le joint est installé entre deux sections de chaussée respectivement supportées par deux éléments de construction contigus (1). Une surface de roulement est formée par un revêtement (2) déposé sur les éléments et interrompu au-dessus de l'intervalle qui les sépare pour former une tranchée. On place au fond de la tranchée un élément d'obturation (4) couvrant l'intervalle, puis on verse des granulats et un liant qui forment un matériau souple (3) après prise. Avant de verser les granulats et le liant, on installe dans la tranchée des armatures qu'on attache aux deux éléments de construction de part et d'autre de l'élément d'obturation. Ces armatures sont ajourées de manière à permettre le passage des granulats. Elles permettent ainsi de renforcer le joint dans le zones où il risque d'être arraché par les forces de traction tendant à écarter les éléments.
