PROCESSES OF FINISHING SLITS OF SURFACE LAYER OF AIRPLANE RUNWAY

摘要

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.
