摘要:
A weatherproofing membrane having a high traction surface is used on a roof or other such location to prevent individuals from slipping. The weatherproofing membrane includes a facer sheet formed of a weatherproofing material and one or more polymer regions disposed on an upper side of the facer sheet. The weatherproofing membrane also includes a layer of modified asphalt disposed on the lower side of the facer sheet and a release backing disposed over the modified asphalt. The polymer is softer than the weatherproofing material and thus provides a higher traction surface than the weatherproofing material of the facer sheet. The polymer includes a low molecular weight polyethylene and an amorphous polyolefin (APO) in respective proportions ranging from about 50/50 to 90/10. The low molecular weight polyethylene and the APO are mixed hot and applied to the facer sheet, for example, using conventional coating techniques.

An underlayment product comprises a fibrous mat having an upper surface and a lower surface. A rubberized asphalt coating is applied to the lower surface of the fibrous mat and extends at least partially into the fibrous mat. In one heavyweight underlayment, an oxidized asphalt coating is applied to the upper and lower surfaces of the fibrous mat generally encapsulating the fibrous mat including the rubberized asphalt coating provided on the lower surface of the fibrous mat. The oxidized asphalt layers may be coated with a release layer such as talc, granules or a polymer. In a lightweight underlayment, a split release sheet or facer segmented to provide a releasable selvedge edge and incorporating a high traction polymer on its surface is applied to the rubberized asphalt.

An asphalt roofing material recycling system and method is used to recycle asphalt materials, such as asphalt shingles and tar paper that include granules, fibers or other particles. The asphalt material is simultaneously heated and milled in a heated milling apparatus, such as a heated ball mill, to reduce the asphalt material granules to a fine mesh in suspension in liquid asphalt. Excess moisture is removed from the asphalt material being recycled, either during heating and milling by continuously venting the heated milling apparatus, or before the heating and milling in a drying apparatus. The heated milling apparatus preferably includes a rotatable milling vessel rotated at an acute angle with respect to the horizontal plane and having an opening that provides continuous venting. The rotatable milling vessel includes a plurality of mixing members, such as rods or paddles, extending from an interior surface and preferably arranged in a helical pattern to force the asphalt material away from the opening. The asphalt material recycling system further includes a storage apparatus for storing reduced asphalt material and a filter apparatus for filtering reduced asphalt and removing foreign objects therefrom.

A system and method for depositing a pattern of media on a moving surface includes a media depositing apparatus that deposits media in a predefined pattern on the moving surface. A media applicator roll having a media receiving region, such as engraved or raised portions, receives the media from a media feeder as the media applicator roll rotates. A media retaining member maintains the media in contact with the media receiving region until the media reach a bottom region of the media applicator roll and are released from the media applicator roll in the predefined pattern onto the moving surface. The method for depositing a pattern of media includes synchronizing the speed of rotation of the media applicator roll with the speed of the moving sheet of material so that the media are precisely deposited as they are released from the media receiving region. The method also includes minimizing the distance that the media must drop from the applicator roll receiving region to the moving surface.
摘要:
A low-cost and easy to manufacture static structure and method for soundproofing walls, floors, and/or ceilings of rooms in new and/or existing construction utilizes an asphalt based flexible membrane as one or more sound absorbing layers which may be applied to an existing wall panel or first applied to one or more unmounted wall panels to form a laminated structure which is then affixed to the walls, floor or ceiling to be soundproofed. The wall panel is preferably gypsum wallboard. Each sound absorbing layer, in addition to soundproofing, may also serve to prevent or at least reduce air or water infiltration to and from the room.
摘要:
An asphalt roofing material recycling system and method is used to recycle new and used (post consumer) asphalt materials, such as asphalt shingles, rolled roofing and tar paper that may include granules, fibers or other particles. The asphalt material, which may be in bundles, is broken up and separated and then provided to a cooled recycling vessel. Dry ice is added along with the asphalt material to be recycled. The dry ice removes any moisture present and super-cools the material making it brittle and easier to chip and break up. The recycle vessel includes a number of high speed shippers having tulip hear chipping teeth as well as one horizontal mixer element which stirs the material and makes sure all material is ground. The resulting course to fine powder can be separated by screening and stored as power or compressed into bricks or briquettes.
摘要:
An asphalt roofing material recycling system and method is used to recycle new and used asphalt materials. The asphalt material is broken up and separated. Dry ice may be added to the recycler and/or a jacket coolant used to cool the recycling vessel. The recycle vessel includes a number of high speed choppers having a blunt end as well as a horizontal mixer element with paddles. The recycled asphalt material is provided to a screener that may feature a plurality of sloping levels, each level including a tray below a screen and balls located within the tray that bounce due to vibration to prevent clogging of the screener. A second processing trip involving gravity feeding the material to be further recycled into a cutter with knife edges to further break down the size of the asphalt material is used for large particles that do not pass through the screener.

摘要:
A recycled asphalt roofing material for use on sloped roofs, which provides the required elevated melt point without using prior art methods of oxidizing the asphalt prior to incorporation into the roofing material is provided. The recycled asphalt roofing material is made up of approximately 30% flux asphalt and approximately 70% reclaimed asphalt roofing material. The fibrous backing in the reclaimed material modifies the asphalt in such a way as to provide the required elevated melt point. The manufacturing process for recycled fiberglass mat-based roll and shingle roofing, in its preferred embodiment, consists of impregnating a roofing material backbone, such as a fiberglass or polyester mat with recycled asphalt material to form inner and outer layers of recycled material and then applying optional second inner and outer layers of standard asphalt coating to the inner and outer layers of the recycled material. The second coating encapsulates and seals the recycled material and thus ensures that the recycled roofing material will have the same longevity as prior art asphalt roofing materials.
