Disclosed is a composite bridge deck waterproofing construction method. The composite bridge deck waterproofing construction method of the present invention comprises the following steps of: applying a primer on a bridge deck to be a construction target; forming a coating film waterproof layer by applying a coating material composition on the bridge deck to which the primer is applied; and attaching a grid member and/or a waterproof sheet on the coating film waterproof layer. The coating material composition includes: an asphalt; a petroleum hydrocarbon resin; and a styrene-butadiene rubber. An objective of the present invention is to provide the composite bridge deck waterproofing construction method capable of improving construction quality. 복합식 교면 방수 공법이 개시된다. 본 발명의 복합식 교면 방수 공법은 시공 대상이 되는 교면 위에 프라이머를 도포하는 단계, 상기 프라이머가 도포된 상기 교면 위에 도막재 조성물을 도포하여 도막 방수층을 형성하는 단계, 및 상기 도막 방수층 위에 그리드 부재 및/또는 방수 시트를 부착하는 단계를 포함하고, 상기 도막재 조성물은 아스팔트, 석유탄화수소 수지 및 스티렌-부타디엔 고무를 구성성분으로 포함한다.
