WATERPROOF PAVING CONSTRUCTION METHOD FOR FLOOR SLAB, AND ITS STRUCTURE

摘要

PROBLEM TO BE SOLVED: To notably improve the service durability of a floor slab by enhancing the adhesive strength of a secondary layer to a primary layer to suppress the degradation of waterproofing performance caused by bulging or separation while using a low-cost material such as ethylene ethyl acrylate (EEA) as a forming material for the secondary adhesive layer. SOLUTION: In this waterproof paving construction method, a wet face adhesive layer 2, a waterproof layer 3 formed of a two-liquid mixed quick setting liquid resin, and a primary adhesive layer 4A formed of a urethane-based resin adhesive, are formed in this order on the floor slab 1, and then 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 to thereby form the secondary adhesive layer 4B between the primary adhesive layer 4A and the asphalt surface layer paving body 5. An adhesive containing butadiene modified polyol is used as the urethane-based resin adhesive. COPYRIGHT: (C)2004,JPO
