The present invention relates to an asphalt composition containing asphalt, cellulose, and a polyester.

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

A superstructure for a traffic surface is provided, the superstructure including a base layer of a mastic asphalt, and an intermediate layer of a porous asphalt arranged on the base layer, wherein the base layer seals a lower side of the intermediate layer at least in a liquid-tight manner. The superstructure comprises a top layer of a mastic asphalt arranged on the intermediate layer, wherein the top layer seals an upper side of the intermediate layer at least in a liquid-tight manner. The superstructure includes at least one sealing wall of a mastic asphalt arranged on at least one side surface of the intermediate layer, wherein the at least one sealing wall connects the base layer to the top layer and seals the at least one side surface in at least a liquid-tight manner. A method for manufacturing the superstructure is also provided.

A permeable pavement system including a permeable pavement composition and a related method are provided. The permeable pavement system includes a first layer of a permeable pavement composition including a quantity of a first permeable pavement material and a quantity of cured carbon fiber composite material (CCFCM) incorporated therewith, the first layer defining a first surface; and a second layer of a second permeable pavement material deposited over a substantial entirety of and covering the first surface of the first layer of the permeable pavement composition, wherein the first layer interfaces with the second layer to at least strengthen the permeable pavement system.

The present application relates generally to bio-adhesive components isolated from bio-oil prepared from animal waste, methods of preparation of the bio-adhesive components and uses thereof. Such uses include, but are not limited to, asphalt bio-binders, bio-adhesion promoters, asphalt bio-rejuvenators, asphalt bio-extenders, bio-asphalt as well as uses in roofing, soil stabilization, crack and joint sealing and flooring adhesives.

An asphalt concrete composition having improved waterproof performance, and a construction method using the composition. The composition includes 100 parts by weight of virgin asphalt, 5 to 25 parts by weight of styrene isoprene styrene, 5 to 15 parts by weight of petroleum resin, 250 to 1,000 parts by weight of reclaimed asphalt pavement, 1 to 10 parts by of a performance improving agent, 250 to 1,000 parts by weight of virgin aggregate, 30 to 150 parts by weight of fine powder aggregate, and 0.1 to 2 parts by weight of cellulose fiber. The composition's waterproof performance is due to its high cohesion and adhesion. The composition is durable and is not easily rutted, aged and/or stripped. In addition, the composition has a performance grade of PG 82-34, can prevent water penetration and potholes, and enables a placement process to be easily performed at low costs.
