    摘要: An improved asphalt composition is provided with the addition of a graft copolymer resin comprising a rubbery polymeric substrate and a rigid polymeric superstrate. A preferred graft copolymer resin is acrylonitrile-butadiene-styrene copolymer resin. Preferred compositions have increased temperature range performance and/or decreased penetration values as compared to the same compositions not containing the graft copolymer resins. The asphalt compositions may optionally contain a vulcanized rubber, preferably obtained from scrap tires.

    摘要: An aqueous asphaltic emulsion wherein the asphaltic component is either a chemically-modified asphalt or an asphalt-elastomer blend, and the aqueous component contains water, a surfactant, and a high molecular weight, non-ionic, homopolymer of acrylamide. The emulsions find use as crack fillers for concrete or asphaltic roads and the like, or as coating compositions which can be sprayed on a building wall or the like as a waterproofing coating. The incorporation of the acrylamide ingredient into the composition ensures rapid and complete curing of other types of emulsions, and the emulsions possess physical properties and low-temperature flex properties which closely approximate those of the original asphaltic component.
