FIELD: construction. ^ SUBSTANCE: method for reconstruction of combined roof including arrangement of new foundation for roof from dry mix of powdered roof bitumen wastes with cement laid as an even layer on surface of restored roof screed with melt of mix by gas burner to make asphalt crust, is characterised by the fact that an even layer of dry mix from powdered roof bitumen wastes with cement with thickness of 8-10 mm is applied onto separating layer from perforated material or flimsy glass tissue, which form drying diffusion layer on screed of restored roof, and dry mix is heated by gas burner until bitumen in mix fully melts down, and solid water-insulation layer is produced, on cooled surface of which a system of frame templates are arranged in a row with slant walls and inner walls previously lubricated by plastic fat clay, and cavities of these templates for the whole height of their walls are filled with dry mix from powdered roof bitumen wastes and light fillers, surface of laid mix is evened with outer edges of frame template and heated by gas burner until bitumen fully melts down, and even surface is produced from heat insulating asphalt. ^ EFFECT: reduced time required to erect new foundation for bitumen roof, reduction of its prime cost, provides for moisture removal from under roof gap with improvement of operational properties of roof structure of reconstructed roof. ^ 4 cl, 8 dwg |
