Abstract: The article gives comparative results of foreign and domestic studies of traditional and dispersively reinforced asphalt concrete using synthetic fiber fibers with an assessment of the main physical, mechanical and deformation-strength indicators. The basic technical characteristics of various types of fibers used at present for the production of composite building materials are also shown. It is shown that due to dispersed reinforcement, the shear resistance at positive temperatures is increased by 20 %, the rate of crack formation at negative temperatures is reduced, the adhesive bond between the dispersed reinforcement formed in the composition of the asphalt mix and the bitumen film is improved. The introduction of synthetic fibers with an optimally selected composition of asphalt concrete allows to increase the dynamic modulus of elasticity and static plasticity of the material, which leads to an increase in the service life of asphalt concrete pavements.
Keywords: asphalt concrete, reinforcement, fiberglass, properties of reinforced asphalt concrete.
