Effect of Modification of a Copolymer of Ethylene with Vinyl Acetate on the Performance of Cement and Asphalt Concrete Based on It

Chemistry and Technology of Fuels and Oils Aims and scope

This work is devoted to modification of road asphalt with ethylene—vinyl acetate (EVA) copolymer. The mechanisms of change in physicochemical properties of modified asphalts and characteristics of asphalt concrete pavements based on the copolymer-modified asphalt and its content in the binder are deciphered. Modification of the organic binder with EVA copolymer improves the low-temperature and adhesion properties of the asphalt, reduces penetrability and extensibility, and raises softening temperature. Increase in content of vinyl acetate groups in the EVA copolymer from 12.5 to 28% leads to enhancement of deformation resistance and adhesion properties of the copolymer, which is reflected also in the properties of the polymer-asphalt composites. There is a marked change in the asphalt penetration: the higher the EVA concentration and the content of vinyl acetate groups in it, the lower the penetration.
