摘要： An acid-reacted polymer-modified asphalt composition comprises: (A) at least about 80 weight percent, based upon the composition, of an asphalt; (B) about 0.2 to about 15 weight percent, based upon the composition, of a polymer containing available epoxy groups and having an average molecular weight of at least 2000; and (C) an amount of an acid effective for promoting chemical bonding between the asphalt and the polymer. The composition exhibits substantially improved Dynamic Shear Rheometer stiffness values. When tested with a dynamic shear rheometer at temperatures ranging from 42 °C to 82 °C, the composition exibits G*/sin(δ) stiffness values which are at least about 2 times greater than stiffness values for the asphalt without polymer or acid, at least about 1.5 times greater than an asphalt/polymer composition without acid, when tested according to AASHTO TP5, exhibits G' viscous component of complex modulus values about the same as the asphalt/polymer composition without acid, when tested according to AASHTO TP5 at temperatures ranging from 4 °C to 40 °C. The composition also exhibits low temperature creep stiffness and 'm' values about the same as those exhibited by the asphalt without polymer or acid, when tested at low temperatures ranging from -42 °C to O °C according to the SHRP Bending Beam Creep Stiffness test, AASHTO TP1.
