A method for manufacturing a processed asphalt suspension is provided. The method includes dry grinding shingle waste material to a particle size of less than 1 cm, forming ground recycled shingle material, introducing virgin asphalt into a heated slurry tank and mixing the ground recycled shingle material with the virgin asphalt in the heated slurry tank, forming a mixed asphalt slurry, introducing the mixed asphalt slurry into a wet grinding machine, and recovering a processed asphalt suspension comprising particles having a size no greater than about 200 microns. Roofing and paving products manufactured from the processed asphalt suspension are also provided.

System and method for manufacturing asphalt products with recycled asphalt shingles

A modified-asphalt composition prepared by introducing a diene end-capped block copolymer with a molten asphalt composition, where the block copolymer is defined by the formula&#x3b1;-(D-V-d)where each D is independently a polydiene block, each V is independently a vinyl aromatic block, each d is a polydiene end cap, &#x3b1; is a coupling moiety, and x is an integer from 2 to 10.

Polymer-modified asphalt compositions

A modified-asphalt composition prepared by introducing a diene end-capped block copolymer with a molten asphalt composition.

A process for preparing a modified asphalt binder composition, the process comprising mixing asphalt, an unsaturated polymer, and an organothionating agent to form a modified asphalt composition.
