Annotation: Using the method of experimental-statistical modeling, the optimal concentration of ethylene glycidyl acrylate of the Elvaloy-AM brand and polyphosphoric acid PFC-105 in petroleum road bitumen (2% wt. and 0.2% wt., respectively) was determined, and the surface of mineral materials was mechanically activated0.7 % wt. ethylene glycidyl acrylate, at these concentration ratios of modifiers, optimal physical and deformation-strength characteristics of the complex-modified road asphalt concrete are provided in our research. It has been established that the fatigue life of the complex-modified asphalt concrete is 1.5-2 times higher than that of the unmodified one.
Keywords: crushed stone-mastic asphalt concrete, complex modification, deformation and strength properties, durability.
Pages: 4-9.
