Abstract: A method for manufacturing modified asphalt is characterized by adding a dispersion agent such as furfural or vegetable oil to a modifier material and then mixing the modifier material with asphalt. The dispersion agent facilitates dispersion of the modifier through the asphalt to form a homogeneous mixture. A first activator is added to the mixture to produce a devulcanized and stabilized asphalt material having improved rheological, separation and solubility characteristics. A micro activator is also added to the mixture to improve the ductility of the modified asphalt. The modifier material comprises granular crumb rubber or polymer.

Abstract: A stable liquid suspension composition comprising a liquid carrier, a solid fatty acid or a salt thereof, and a solid particulate is disclosed wherein said liquid carrier is selected from the group consisting of oils, olefins, terpenes, glycols, esters, ethers, alcohols, and combinations of any two or more thereof and said liquid carrier, solid fatty acid or salt thereof, and solid particulate are each present in said composition in a stabilizing amount sufficient to produce a stable liquid suspension. Also disclosed is a stable liquid composition comprising a liquid carrier, an oil-soluble polymer, and a solid particulate wherein said liquid carrier is selected from the group consisting of olefins, terpenes, esters, and combinations of any two or more thereof and said liquid carrier, oil-soluble polymer, and solid particulate are each present in said composition in a stabilizing amount sufficient to effect the formation of a stable liquid suspension.
