In reasphalting an asphalted road a cutting implement (9) with a substantially horizontal front edge (15) is inserted under the existing asphalt coating (5). As the cutting implement (9) advances (P1) the asphalt is loosened from the base (3) substantially as a whole. The loosened asphalt (5) is passed to a mixing chamber (25) and mixed with bitumen, thus producing a new asphalt material (10), which is added to the base (3) for the formation of a new asphalt coating (11).

Selon cette invention, lors de la réhabilitation d'une route asphaltée on insère sous la couche d'asphalte existante (5) un instrument de coupe (9) possédant un bord avant sensiblement horizontal (15). A mesure que l'outil de coupe (9) avance (P1), l'asphalte se détache de la base (3) en un bloc sensiblement uni. L'asphalte détaché (5) est acheminé dans une chambre de mélange (25) où il est mélangé au bitume pour donner un nouveau matériau à base d'asphalte (10), qui est ajouté à la base (3) pour former une nouvelle couche d'asphalte (11).
