JOINT WATERPROOFING METHOD OF PAVED ROAD SURFACE AND JOINT WATERPROOFING TAPE

摘要

PROBLEM TO BE SOLVED: To easily install a joint waterproofing tape which is hardly separated from a pavement body of a road surface, does not require heating in installation work, and withstands temperature rise in summer. SOLUTION: A tacky substance formed by mixing a synthetic rubber, a filler and a tackifier has a softening point not lower than 150°C and an interfacial separation strength higher than a cohesive failure strength is extended in the shape of a tape, and the tape is pressed and bonded to joints on the paved road surface.
