Method for sealing the joint between two road parts which are movable relative to each other and are provided with an asphalt road surface, in particular the joint between two bridge roadway parts or between a bridge roadway part and a land-abutment part

摘要

For sealing the join (3) between two road parts (1,2) which are movable relative to each other and are to be provided with, or have already been provided with, an asphalt road surface (4.5), in particular the join between two bridge roadway parts or between a bridge roadway part and a land-abutment part, a recess (6) is made at the site of the join in at least the hot-rolled asphalt covering said parts, and a material with elastic properties is placed in the recess. In order to provide a water-permeable or water-draining and low-noise filling of the recess at the position of the join, without adversely affecting the elasticity and flexibility of said filling, which is necessary to avoid cracks forming, at least the bottom of the recess is covered with an elastic sealing membrane layer (7), a hard strip (8), for example of metal, is placed in said layer above the join, the membrane layer extending over the strip, and the recess above the membrane layer is filled with elastic hot-rolled asphalt (9,10) of which at least the top layer is made of very open elastic hot-rolled asphalt (10).
