MMA A method of constructing a bridge waterproof layer using a hybrid type speedy elastic methyl methacrylate MMA resin and a basalt mesh geogrid to construct a road stretching joint side

The present invention provides a construction method for forming a bridge waterproof layer using a hybrid type ultra-rapid elastic methyl methacrylate (MMA) resin and a basalt mesh geogrid and constructing a side gutter and a road expansion joint side. The construction method for forming a bridge waterproof layer using a hybrid type ultra-rapid elastic methyl methacrylate (MMA) resin and a basalt mesh geogrid and constructing a side gutter and a road expansion joint side includes: a step of removing a deterioration unit on a side gutter of a road; a step of applying a reinforcing primer layer to the upper part of the side gutter of the road in which the deterioration unit is removed; a step of manufacturing a composite for forming a waterproof layer by mixing a first ingredient and a second ingredient, wherein the first ingredient includes 30-60 parts by weight of a methyl methacrylate resin, 10-18 parts by weight of 2-ethylhexyl acrylate, 5-15 parts by weight of a phthalic acid resin, 12-35 parts by weight of butyl methacrylate, and 2-6 parts by weight of butyl acrylate, and the second ingredient includes 2-15 parts by weight of basalt fiber, 30-50 parts by weight of calcium carbonate, 15-55 parts by weight of silica, 0.5-2 parts by weight of benzoyl peroxide, 5-12 parts by weight of silane, and 70-85 parts by weight of cement mortar; and a step of forming a waterproof layer by applying the composite for forming a waterproof layer to the upper part of the reinforcing primer layer and hardening the same. According to the present invention, the construction method for forming a bridge waterproof layer using a hybrid type ultra-rapid elastic methyl methacrylate (MMA) resin and a basalt mesh geogrid and constructing a side gutter and a road expansion joint side can improve rigidity, resistance to salt, and freeze-thawing resistance on a bridge side gutter and a deteriorated road and can prevent a crack and separation by increasing durability on a repeated impact load. Moreover, the construction method for forming a bridge waterproof layer using a hybrid type ultra-rapid elastic methyl methacrylate (MMA) resin and a basalt mesh geogrid and constructing a side gutter and a road expansion joint side can reduce maintenance costs by reducing time for repair work on the side gutter of the road in comparison with an existing invention. 도로 측구의 열화부를 제거하는 단계; 상기 열화부가 제거된 도로 측구의 상부에 강화 프라이머층을 도포하는 단계; 메틸메타크릴레이트 레진30~60중량부, 2-에틸헥실 아크릴레이트 10~18중량부, 프탈산 레진5~15 중량부, 부틸 메타크릴
