WATERPROOF PAVING CONSTRUCTION METHOD FOR FLOOR SLAB, AND ITS STRUCTURE

摘要

PROBLEM TO BE SOLVED: To maintain the service durability of a floor slab of a bridge or the like by preventing the damage and rupture of a waterproof layer caused by impulsive load and repeated stress while enhancing adhesive performance to prevent the occurrence of defects such as bulging as well as efficiently constructing prescribed waterproof pavement. SOLUTION: A wet face adhesive layer 2, the waterproof layer 3 formed of a two-liquid mixed quick setting liquid resin, and a primary adhesive layer 4A formed of a soft resin adhesive, are formed in this order on the floor slab 1, and a powdery and granular or pellet-like heat-fusible adhesive 6 is spread on the primary adhesive layer 4A. Paving of a heating asphalt paving body 5 is carried out thereon to melt the heat-fusible adhesive 6 to flow with the heat of the heating asphalt paving body 5. A secondary adhesive layer 4B is thereby formed between the primary adhesive layer 4A and the asphalt paving body 5 to bond and integrate them. COPYRIGHT: (C)2004,JPO
