PROBLEM TO BE SOLVED: To eliminate a factor in the generation of cracks in floor slab concrete in the case of a delay in asphalt pavement on the floor slab concrete. SOLUTION: A protective pavement method for floor slab concrete comprises: a concrete placing process for placing concrete, which is mixed in a designed manner, on floor slab; a nonbleeding concrete layer forming process for forming a nonbleeding concrete layer on the levee crown of the placed floor slab concrete; a sheet laying process for laying an impervious sheet on the surface of the formed nonbleeding concrete layer; and a pavement process for paving a heated asphalt mixture with an adhesive on the laid impervious sheet. After the completion of the sheet laying process, this method is commonly applicable to a road for construction work and the like in a state that the sheet is laid and left as it is before the performance of the pavement process.
