Summary:The present invention relates to a heating complex waterproofing method for a bridge surface. The heating complex waterproofing method for a bridge surface, which is manufactured with a coating waterproof material and an improved asphalt waterproof sheet formed on the waterproof material, includes: a primer layer forming step of forming a primer layer on the floor of a waterproofing target bridge surface; a coating waterproof material forming step of forming the coating waterproof material on the primer layer; and a waterproof sheet attaching step of attaching the improved asphalt waterproof sheet onto the coating waterproof material before the coating waterproof material hardens. In the coating waterproof material forming step, primary synthetic rubber and synthetic polymer resin are manufactured and then the materials are used to manufacture the coating waterproof material. The primary synthetic rubber includes: 10-20 wt% of natural rubber (NR) as a mixed compatibilizer; 20-30 wt% of SBS as a binder; 20-30 wt% of chloroprene rubber (CR) as a strength enhancer; 20-30 wt% of LDPE as a hardness enhancer; and 5-15 wt% of a plasticizer (DOTP). The synthetic polymer resin includes: 50-80 wt% of polymer resin LDPE/TPO as a hardness enhancer, which is made by pre-mixing LDPE and olefin resin at a weight ratio of 1:1 to minimize plastic deformation caused by a repetitive wheel load; and 20-50 wt% of NBR for improving compatibility with the primary synthetic rubber. The coating waterproof material is manufactured by mixing and stirring 10-15 wt% of the primary synthetic rubber, 5-12 wt% of the synthetic polymer resin, 45-69 wt% of straight asphalt, 8-15 wt% of SBS, 5-8 wt% of plasticizer, and 3-7 wt% of filler. 본 발명은 교면용 가열 복합방수공법에 관한 것으로, 도막방수재 및 상기 도막방수재 상부에 형성되는 개량아스팔트 방수시트로 제조되는 교면용 복합방수공법에 있어서, 방수 대상 교면 바닥에 프라이머층을 프라이머층 형성단계; 상기 프라이머층 상에 도막방수재를 형성하는 도막방수재 형성단계; 상기 도막방수재 상에 도막방수재가 경화되기 전에 개량아스팔트 방수시트를 부착하는 방수시트 부착단계를 포함하되, 상기 도막방수재 형성단계는 1차합성고무 및 합성고분자수지 제조 후 이를 이용하여 도막방수재를 제조하는 데, 1차합성고무 제조는 혼합 상용화제로 천연고무(NR) 10~20중량%, 바인더로 SBS 20~30 중량%, 강도강화제로 클로로프렌고무(CR) 20~30중량%, 경도강화제로 LDPE 20~30중량%, 가소재(DOTP) 5~15중량%를 포함되도록 제조하고, 합성 고분자수지 제조는 반복 윤하중에 의한 소성변형을 최소화 하기 위하여 경도 강화제로 LDPE 및 올레핀 수지 1:1 중량비율로 선배합 후 상기 선배합된 고분자 수지 LDPE/TPO 50~80 중량%, 1차합성고무와 상용성을 향상시키기 위한 NBR 20~50 중량%를 포함되도록 제조하며, 제조된 1차 합성고무 10~15중량%에 합성고분자 수지 5~12중량%, 스트레이트 아스팔트 45~69중량%, SBS 8~15중량%, 가소재 5~8중량%, 충진제 3~7중량%를 교반하여 제조하는 것을 특징으로 하는 교면용 가열 복합방수공법을 제공한다.
