Abstract: The article experimentally proves that the introduction of dispersed reinforcement in the form of glass fiber, polypropylene and chrysotile-asbestos fibers into asphalt concrete mixtures can significantly increase the fatigue life of dispersed-reinforced asphalt concrete under the influence of short-term cyclic and long-term static loads. It has been established that the optimal content of polypropylene fiber (0.7 % wt.) made it possible to increase the fatigue life of asphalt concrete type «Gx» by 1.6 times. The optimal content of glass fiber and chrysotile-asbestos fibers (1.5 % wt.) made it possible to increase the fatigue life of dispersion-reinforced hot asphalt concrete under short-term cyclic loading by 32 and 22 %, respectively. The introduction of these fibers into a fine-grained asphalt concrete mix of type «B» made it possible to increase, on average, 1.9-2.1 times the fatigue life under the influence of long-term static loads.
