The invention relates to a recycled concrete laminated slab containing prestressed FRP rib bundle fibers and a manufacturing method thereof. The recycled concrete laminated slab comprises a concrete lower slab body; a transversely and longitudinally staggered steel reinforcement framework is erected in the concrete lower slab body; a plurality of inverted V-shaped convex ribs are uniformly distributed at the upper end of the steel reinforcement framework; V-shaped openings of the convex ribs face downwards; the end parts of the convex ribs are fixedly connected with the steel reinforcement framework; the top ends of the convex ribs protrude out of the concrete lower slab body and are combined with a concrete upper slab body poured at the upper end of the concrete lower slab body; a plurality of pre-embedded pipes arranged in parallel in the horizontal direction are embedded in the concrete lower slab body; and FRP rib bundles are inserted in pre-embedded pipe holes. According to the recycled concrete laminate
