PROBLEM TO BE SOLVED: To provide a new waterproof construction method for a floor slab, wherein an asphalt paving body to be obtained is free from separation, swell or the like of a waterproof layer due to a vehicle load etc. and cracks and the like in asphalt. SOLUTION: When the floor slab is constructed in bridge sections of a roadway, a railroad, a pedestrian bridge and the like, the waterproof layer and an asphalt pavement are bonded together by interposing a tack sheet material between the water proof layer and the asphalt pavement, so that the floor slab, the waterproof layer and the asphalt pavement can be integrated and firmly bonded together. In the tack sheet material, a thermoplastic synthetic resin is molded like a sheet in a spider's web shape or nonwoven fabric shape, or molded in a tape shape or bead shape on a nonwoven fabric composed of polyester fibers etc. or on a net-like woven fabric. Firmness of the tack sheet material like this prevents deflection during an operation, a crease, a twist, etc., brings about construction workability excellent in various aspects, and enables an increase in working speed. Additionally, when interposed on a top surface of the waterproof layer, the tack sheet material does not cause the retention of air and the twist. COPYRIGHT: (C)2005,JPO&NCIPI |
