Annotation: The physical and mechanical properties of complex-modified ethylene glycidylacrylate hot asphalt concrete containing surface-activated 0,7 % by weight of ethylene glycidylacrylate mineral materials (crushed stone, sand, mineral powder in fine-grained asphalt concrete type B) and modified petroleum road bitumen (2 % wt. ethylene glycidylacrylate together with 0,2 % wt. polyphosphoric acid) have been determined and investigated. The asphalt polymer concrete modified holistically by ethylene glycol acrylate is characterized by Marshall resistance, Р = 30 kH; higher resistance to rutting formation, 23…36 % less than unmodified asphalt concrete; water resistance after 90 days of water saturation is Kws = 0,91; the frost resistance coefficient after 100 cycles is F = 0,88, the coefficient of heat aging after 2000 hours (the temperature of heating is 75 °C under UV irradiation) is Kag = 1,2.
Keywords: asphalt polymer concrete, ethyleneglycidylacrylate, composition and structure, physical and mechanical properties.
