Abstract: The work is devoted to the development of compositions of road modified asphalt concrete of increased durability with a complex modified structure with cationic latex Butonal NS 198. It has been experimentally established that for fine-grained asphalt concrete of type «В» containing BND 40/60 bitumen modified with 3 % cationic latex Butonal NS 198, the optimal concentration of Butonal NS 198 on the surface of mineral materials: crushed stone, sand, mineral powder is 2.0 % by weight. Asphalt concrete mixtures complexly modified with NS 198 Bud compared with mixtures with modified NS 198 organic binder Bud are characterized by an increase in density up to 2 348 kg/m3, compressive strength at 20 °C – up to 5.5 MPa, at 50 °C – up to 1.94 MPa, as well as a decrease in water saturation up to 2.03 % of volume.
Keywords: bitumen, modification, cationic latex Butonal NS 198, asphalt concrete with complex-modified micro-, meso- and macrostructure.
