The purpose of the present invention is to provide a rapid hardening type waterproofing and anticorrosive bridge deck structure which improves waterproofing and anticorrosion effects between the bridge decks and the asphalt (6) when paving an asphalt (6) on various bridge decks such as a steel deck plate, a concrete upper plate, and an FRP upper plate, gives shear adhesion force for preventing an asphalt slip phenomenon, and enables construction and repairing operations to be rapidly performed. The rapid hardening type waterproofing and anticorrosive bridge deck structure of the present invention comprises: a complex waterproofing and anticorrosive agent for heavy duty coating (2) which is uniformly coated on a surface-treated bridge deck; silica (3) which is scattered on a top portion of the complex waterproofing and anticorrosive agent for heavy duty coating; a special coating agent (4) which is coated on a top surface where silica (3) is scattered and bonded such that silica (3) is impregnated and fixed between the complex waterproofing and anticorrosive agent for heavy duty coating (2) and the special coating agent (4); a tack coating agent (5) which is formed of an asphalt emulsion sprayed onto a top surface of the special coating agent (4); and the asphalt (6) which is paved and installed on a top portion after drying the tack coating agent (5). The rapid hardening type waterproofing and anticorrosive bridge deck structure according to the present invention can obtain a plurality of effects that adhesive force and coupling force among the asphalt (6) and a waterproofing and anticorrosive layer and a bridge upper plate (1) can be improved during pavement of the bridge decks, excellent waterproofing and anticorrosive properties are provided by using a rapid hardening type complex waterproofing and anticorrosive agent for heavy duty coating that is rapidly hardened, and coating of a primer layer that is a primer is removed to simplify working process and minimize working time, thereby enabling accident risk or the like to be resolved at a single stroke. 본 발명은 강상판, 콘크리트상판, FRP상판 등의 각종 교면에 아스팔트(6)를 포장할 시 교면과 아스팔트(6) 사이에서 방수, 방식효과의 향상과 아스팔트 밀림현상을 방지하는 전단접착력의 부여 및 신속한 시공 및 보수가 가능토록 한 속경형 교면 방수방식구조를 제공코자 하는 것으로서, 상기의 본 발명은 표면 처리된 교면에 균일하게 도포된 중방식용 복합 방수 및 방식제(2)와, 상기 중방식용 방수 및 방식제의 상부에 살포된 규사(3)와, 상기 규사(3) 살포 후 접착된 상면으로 도포되어 중방식용 복합 방수 및 방식제(2)와의 사이에서 규사(3)가 함침 고정되게 구성된 특수코팅제(4)와 상기 특수코팅제(4) 상면에 살포된 아스팔트 유제로 이루어진 택코팅제(5)와, 상기 택코팅제(5) 건조 후 상부로 포장 설치된 아스팔트(6)가 포함된 것을 특징으로 하며, 이에 의하면 교면포장 시 아스팔트(6)와 방수방식층 및 교량상판(1)과의 접착력 및 결합력 향상시킬 수 있으며, 신속하게 경화되는 속경형의 중방식용 복합 방수 및 방식제를 사용하여 우수한 방수성과 방식성을 제공하면서 하도제인 프라이머층의 도포를 없애면서 작업공정의 단순화과 작업소요시간을 최소화시켜서 사고 위험성 등을 일거에 해소할 수 있는 등 다수의 효과를 득할 수 있다.
