Abstract: Bituminous paving mixtures containing lubricating agents or additives may be prepared at hot mix temperatures and cooled, paved and compacted at temperatures 10-55 Celsius degrees lower than the hot mix temperatures. The increased temperature range between the hot mix temperatures and the paving and compacting temperatures is facilitated by the improved compacting properties of the paving mixture when it includes the lubricating agents or additives.

Abstract: An acid-reacted polymer-modified asphalt composition comprising (1) at least about 80 weight percent, based upon the composition, of an asphalt; (ii) about 0.2 to about 15 weight percent, based upon the composition, of a polymer containing available epoxy groups; and (iii) an amount of an acid effective for promoting chemical bonding between the asphalt and the polymer, wherein the composition exhibits substantially improved Dynamic Shear Rheometer stiffness values without an appreciable loss in the G″ viscous component of complex modulus, and low temperature creep stiffness and “m” values.
