Modification of Asphalt Oxidation and Binders with Polymers
Asphalt can be modified by polymers, oligomers, and waxes made from polymeric material. The addition of polymer, oligomer, or wax can increase the softening point of the asphalt, decrease the penetration of the asphalt, and/or shorten the oxidation of the asphalt. In some embodiments, polymer, oligomer, or wax is added to an oxidized asphalt. The polymer, oligomer, or wax can be made by catalytic depolymerization and/or thermal degradation of polymeric material. The polymeric material can be polystyrene, polypropylene, polyethylene, a combination of polypropylene and polyethylene or recycled plastics. In some embodiments, addition of the polymer, oligomer, or wax improves the performance grade of a paving asphalt binder alone or in combination with other modifiers such as ground tire rubber and polymers. The addition of wax can increase the high service temperature of the asphalt binder.
