Abstract (en)
The screed (table) for compacting and finishing comprises a central element (11) and two lateral elements (12a, 12b) which are movable in the transverse direction relative to the central element (11). Each of the lateral parts (12a, 12b) of the compacting screed (table) carries a boom (18a, 18b) for spraying binder. The booms (18a, 18b) form a spraying assembly whose width is variable as a function of the width of the compacting screed (table). A trough (25), integral with one of the booms (18a) and arranged substantially over its entire length, makes it possible to recover the bitumen jets (22) of the boom (18a) in the overlap zone of length L between the booms (18a) and (18b). <IMAGE>
Abstract (fr)
La table de compactage et de finissage comporte un élément central (11) et deux éléments latéraux (12a, 12b) mobiles dans la direction transversale par rapport à l'élément central (11). Chacune des parties latérales (12a, 12b) de la table de compactage porte une rampe de répandage de liant (18a, 18b). Les rampes (18a, 18b) constituent un ensemble de répandage à largeur variable en fonction de la largeur de la table de compactage. Une auge (25) solidaire de l'une des rampes (18b) et disposée substantiellement sur toute sa longueur permet de récupérer les jets de bitume (22) de la rampe (18a) dans la zone de recouvrement de longueur L entre les rampes (18a) et (18b).
