The disclosure embraces a membrane paving construction comprising an asphalt-impregnated body, pelt or mat of fibers, preferably glass fibers, and a method of making same wherein the membrane construction is prefabricated or partially fabricated for use in asphalt paving construction such as paving for highways, bridge decks, driveways, runways, parking lots and the like, as a paving wear surface or for repairing a wear surface or as a membrane construction upon which is superposed a wear surface of asphalt aggregate or the like, the membrane construction being in the form of a rolled-up body or in the form of a thin high density planar board or sheet which may be conveyed in such forms to an installation site and disposed on a substrate in a minimum of time in initial installation of paving or in the repair of asphalt paving.
A prefabricated unitary section of membrane construction for use in paving comprising a sheet-like body of unbonded fibers, said body being impregnated with heated asphalt material, flake glass in the impregnated sheet-like body in an amount in a range of one percent and ten percent by weight, said section being cooled to set the asphalt material.
A prefabricated unitary section of membrane construction for use in paving comprising a sheet-like body of unbonded fibers, said body of fibers being impregnated with heated asphalt material, a layer of asphalt containing flake glass disposed on and adhered to a surface of the asphalt-impregnated sheet-like body of fibers, said section being cooled to set the asphalt material.
