ASPHALT MODIFYING MATERIAL HAVING SPECIFIC COMPOSITION, MODIFIED ASPHALT MIXTURE AND METHOD OF PAVEMENT USING THE SAME, AND COMPOSITION

摘要

An asphalt modifying material which comprises an elastomer and a (meth)acrylic resin, wherein the (meth)acrylic resin is contained in a proportion of 0.01 to 1.5 parts by weight relative to 1.0 parts by weight of the elastomer; a modified asphalt and a modified asphalt mixture comprising the asphalt modifying material; a method of asphalt pavement using the modified asphalt mixture; and a composition comprising a styrenic elastomer and a (meth)acrylic resin. The asphalt modifying material is suppressed with respect to the phase separation between asphalt and the material and exhibits improved toughness and tenacity without detriment to its workability or to its production cost, and further has enhanced adhesion to an aggregate, which leads to the excellent durability of the resultant pavement.
