MMA BRIDGE DECK WATERPROOFING MATERIAL COMPRISING MMA RESIN COMPOSITION AND BRIDGE DECK WATERPROOFING CONSTRUCTION METHOD USING THE SAME
The present invention relates to a methyl methacrylate (MMA) resin-based bridge deck waterproofing composition and a bridge deck waterproofing method using the same. More specifically, the MMA resin-based bridge deck waterproofing composition comprises: 100 parts by weight of an organic binder including 70 to 80 wt% of an MMA resin, 5 to 15 wt% of an unsaturated polyester (UPR) resin, 5 to 15 wt% of an expanded polystyrene (EPS) resin, and 0.1 to 0.5 wt% of a methyl ethyl ketone peroxide (MEKPO) hardener; 80 to 100 parts by weight of an inorganic binder having waste garnet fine aggregate obtained by mixing silica sand No. 9 (0.08 to 0.125 mm of a particle size) and No. 8 sand (0.125 to 0.18 mm of a particle size) at a 1:1 weight ratio; 10 to 30 parts by weight of a calcium carbonate filler; and 2 to 5 parts by weight of reinforcing fiber, thereby strengthening the adhesion of the unsaturated polyester resin to the bridge surface, improving the durability of the expanded polystyrene (EPS) resin against deterioration due to solar heat shielding, and improving the strength of the waterproof layer of waste garnet fine aggregate.
