Abstract
A chemically-modified asphalt composition formed by reaction of an asphalt, a polycarboxylic acid or anhydride and an organic polyalcohol. The resulting polyester-modified asphalt composition can be cross linked using a vulcanizing agent to form hard rigid bodies which can be reinforced with reinforcements and/or fillers, notably including glass fibers.
