The invention discloses a bridge and tunnel fiber composite pouring flexible waterproof pavement and construction method. A bridge and tunnel fiber composite pouring flexible waterproof pavement is of a layered composite structure. A two-stage thermoplastic epoxy resin waterproof bonding layer, a fiber composite pouring type asphalt concrete lower surface layer, a gravel embedding layer, a superimposed fiber epoxy resin bonding layer and a fiber composite resin upper surface layer are sequentially arranged on a steel bridge deck slab; the fiber composite pouring type asphalt concrete lower surface layer is prepared by mixing pouring type asphalt concrete with carbon fibers; and the gravel embedding layer and the fiber composite pouring type asphalt concrete are synchronously constructed. The fiber composite pouring type asphalt concrete has good deformation following performance on the bridge steel bridge deck slab, and the problem that a large-span and large-flexibility bridge steel bridge deck system paveme
