A method of forming an asphalt mixture includes mixing a polyol with a bio-source material to form a bio-asphalt. The method can further include mixing the bio-asphalt with a bitumen source different from the bio-asphalt to form an asphalt mixture. The bio-source material can include an oil, such as a vegetable oil, an animal fat, or any combination thereof. The bitumen source can include a petroleum-based asphalt. The method can further include adding a modifier, such as a fatty acid, a polycarboxylic acid, a polyacrylic acid, a polyacrylate comprising a copolymer, or any combination thereof. Moreover, a roofing grade asphalt mixture includes a bio-asphalt. The bio-asphalt includes an alkyd, wherein the alkyd is a reaction product of a polyol and a bio-source material. The roofing grade asphalt mixture further includes a bitumen source material and particles.

A roofing membrane includes a membrane layer. An adhesive layer is adhered to a first side of the membrane layer and a layer of granules is adhered to the first adhesive layer.

A roof structure comprises a roof membrane and a roof substrate. A first surface of the roof membrane is adhered to the roof substrate by a two component adhesive, the adhesive being capable of adhering the first surface of the roof membrane to the roof substrate without the use of a high VOC solvent. The two component adhesive includes a Michael donor and a Michael acceptor, and the Michael donor and the Michael acceptor react to form an adhesive film.

A carrier material includes at least a first thermoplastic fiber layer and a second thermoplastic fiber layer. At least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection. The carrier material can be used in bituminous roofing membranes, roofing underlayment sheets, carriers for filter media, primary backings for tufted carpets and (cushion) vinyl floor coverings.

Disclosed is a hybrid composite construction material and a process for creating it. The substrate used to create the new hybrid material has the same compound applied on at least the side lap area on the top side of the substrate and at least a portion of the back side of the substrate. The substrate can be pre-saturated with a selected compound prior to applying the same compound on at least the side lap area on the top side of the substrate and at least a portion of the back side of the substrate. The processes to create the product and other embodiments is also disclosed.

During installation of a single-ply roofing membrane, the surface of the membrane can be protected from dirt, scratches and scrapes by a protective sheet which also provides other beneficial attributes that aid an installer. A roof laminate includes a roof membrane and a protective sheet is removably affixed thereto. The sheet includes at least a first layer directly secured to a second layer. The first layer provides at least one of UV protection, anti-slip, and anti-glare to the roof laminate and so aids the installer in at least one of those respects. The second layer is removably affixed to the roof membrane.
