Annotation: It is shown that the rational way to improve the durability of asphalt concrete is a modification of bitumen with polymers of different origin and surface activation of the mineral materials oligomers and polymers. The work carried out modification of the oil bitumen 60/90, while the two modifiers: methylstyrenebutadiene rubber SKMS-30 and ethyleneglycidylacrylate (Elvaloy AM). It was found that the optimal concentration of polymer in bitumen should be: 60/90+2 % by weight Elvaloy AM thermostating at 4 hours and 0.5–1.0 % by weight SKMS-30, and further increase the concentration SKMS-30 reduces adhesion bitumenpolymer binder to mineral materials. The use of two polymers: methyl styrene butadiene rubber SKMS-30 and ethyleneglycidylacrylate (Elvaloy AM) for the modification of binders improves the technological properties of organic binders and performance indicators of quality of asphalt polymer concretes.
Keywords: asphalt polymer concrete, road oil bitumen, mineral material, ethyleneglycidylacrylate, methylstyrenebutadiene rubber, bitumenpolymer binder.
