A pavement rejuvenating and/or conditioning composition in the form of an aqueous-based emulsion or jelly. More particularly, bituminous pavement rejuvenators and pavement dressing conditioners are made into emulsions or jellies by agitating the rejuvenators and/or conditioners in cationically- or anionically-modified aqueous solvents. These solvents include aqueous polyvinylalcohol; aqueous amines; aqueous compounded amines such as those available from Akzo Chemicals and sold under the tradename Redicote (i.e., Redicote E-9) or those available from B.F. Goodrich Chemical Co. and sold under the tradename Carbopol; and aqueous solutions of aliphatic fatty acids and caustic (usually sodium hydroxide). When the emulsifying agent concentration in the solution is increased, the solution may be used to form jellied products, whereas more dilute aqueous solutions of the emulsifying agents are suitable for preparing lower viscosity emulsions of the rejuvenating and conditioning compositions.
