A process of finishing slits in the surface layer of a runway involves a first step in which a slit (11) is heated such that the surface of the slit (11) is dry, and that the capillary holes of the slit (11) are opened up. The surface of the slit (11) is then provided with a coating (50) of an asphalt synthetic agent. The coating (50) is subsequently heated to cause the molecules of the asphalt synthetic agent to diffuse into the capillary holes of the slit (11), thereby preventing water from finding its way into the gradation layer (A) of the runway. The slit (11) is provided with a soft interface (60) capable of preventing the water from finiding its way into the slits of the surface layer of the runway. The soft interface (60) is securely attached to the slits.
L'invention concerne un procédé pour retoucher toutes les fentes de la couche superficielle d'une piste d'aviation. Ce procédé comprend une première étape où une fente est chauffée de manière à ce que sa surface soit sèche et que les orifices capillaires de la fente soient ouverts. La surface de la fente est alors recouverte d'un agent en asphalte synthétique. Ce revêtement est ensuite chauffé pour que les molécules de l'agent en asphalte synthétique se diffusent dans les orifices capillaires de la fente, pour empêcher ainsi l'eau de s'infiltrer dans la couche de terrassement de la piste. Entre temps, la fente est dotée d'une interface souple apte à prévenir l'infiltration de l'eau dans les fentes de la couche superficielle de la piste. Cette interface souple reste solidement liée aux fentes, quels que soient les changements climatiques.
