Abstract: A asphalt binder modifier or a stand-alone asphalt binder and the method of making the asphalt binder or binder modifier are disclosed. The asphalt modifier or binder consisting of treated re-refined engine oil bottoms/VTB's treated by injecting air into re-refining engine oil bottoms/VTB's at temperatures between 150° F. and 550° F. The re-refined engine oil can be processed with ground tire rubber. The binder modifier was blended with various paving and roofing asphalts to form performance-enhanced modified asphalt binders used in paving, roofing, and industrial products.

Abstract: This invention is directed to an improved clays-stabilized bituminous emulsion composition for use as a surface coating and the like. Such an emulsion includes about 90.0-99.95 parts by weight of an aqueous bituminous emulsion and about 0.05-10.0 parts by weight of a cohesion promoting additive selected from the group consisting of amines, amidoamines and blends thereof having the structural formulaX.[R(NH R").sub.n NH.sub.2 ]+Y.[R'"C(O) (NH.sub.m R.sup.IV).sub.o ]whereinX and Y are weight percentages such that X+Y=100% of the active, nitrogenous components,R is a lipophile selected from the group consisting ofR'-andR'OR"-,R' is an alkyl chain having 3-26 carbon atoms,R" is a hydrocarbon fragment 2-6 carbon atoms,n is an integer from 0-4,R'" is selected from the group consisting of an alkyl chain having 3-26 carbon atoms, and an alkenyl chain having 3-44 carbon atoms, andR.sup.

Abstract: Properties and cold applicability of asphalt elastomer compositions are substantially improved by utilizing cyclohexanone therein as a co-solvent.
