A pigment and method for making a pigment comprising a milled elastomer, wherein the milled elastomer has a D50 particle size of between about 5 and about 50 microns. A coating of the pigment has a smoothness of about 3 or less. The pigment is prepared by providing an elastomer; and milling the elastomer in the presence of milling media and solvent at a temperature from about 30 C. to about 70 C. The elastomer is insoluble in the solvent. The method for preparing the pigment from an elastomer comprises the steps of: providing an elastomer; and milling the elastomer in a media mill in the presence of milling media and solvent at a temperature from about 30 C. to about 70 C. The diameter of the milling media is from about 0.5 mm to about 10 mm, and the elastomer is insoluble in the solvent.

A combination of antioxidants and method of incorporating the antioxidants into an asphalt binder to make a modified asphalt binder are described. The antioxidants comprise a thioester and an aldehyde. The aldehyde and thioester, in a ratio between about 1:100 and about 100:1 parts by weight, are added to an asphalt binder. An acidic catalyst is also added in a concentration between about 0.1 wt % and about 18 wt % of the asphalt binder. The antioxidants, asphalt binder, and catalyst are mixed at a temperature between about 85 C. and about 135 C. for a time between about 30 minutes and about 6 hours. The antioxidants are capable of improving the performance grade of the asphalt binder. The modified asphalt binder possesses superior resistance to oxidative age hardening compared to other modified asphalt binder compositions that incorporate various antioxidants.
