Properties of Bitumen Composition Modified by Petroleum Resins

It was advised to use aliphatic, cycloaliphatic, aromatic petroleum resins and their derivatives obtained by oxidation of with a mixture hydrogen peroxide acetic acid as bitumen polymer-modifiers. Petroleum were ionic polymerization unsaturated compounds liquid pyrolysis products under the influence titanium tetrachloride-diethylaluminium chloride catalyst. established that maximum values adhesion modified coatings metal substrates, corresponding minimum wetting angle surface coated solutions compositions different content polymer modifier achieved using oxidized resins. All have low water absorptivity high resistance, alkali resistance salt which allow them protective
