Abstract:
A modified bitumen consisting of a polyurethane wherein the polyisocyanate or polyisocyanate-dominated polyurethane prepolymer (or prepolymers) is first reacted with the bitumen to take advantage of the bitumen's hydroxyl and amine functionality and form an isocyanate-bitumen adduct to form a weatherproofing product.

Claim (Index 21):
An actively modified polymer-modified bitumen formulation comprising:\n 25-75 wt. % of a first component that consists of bitumen, coal tar, or combinations thereof; 1-49 wt. % of a second component that consists of polyurethane, or blend of polyurethane and rubber, said polyurethane including isocyanate end groups, said polyurethane formed from at least one polyisocyanate compound and at least one polyol, said polyol includes a molecular weight compound of at least 1000, a content of said polyol creating a NCO/OH equivalent ratio of no less than 2:1 in said bitumen formulation; and, 1-66 wt. % of a filler; wherein a weight percent of said first component is greater than a weight percent of said second component, said isocyanate end groups in said polyurethane reacting with hydroxyl end groups in said bitumen, said coal tar, or combinations thereof, said formulation can be used to create a membrane having improved mineral retention and weatherability.
