Fatigue Durability Research Crushed Stone-Mastic Asphalt Concrete
Abstract: The article presents the results of experimental studies of the fatigue life of crushed stone-mastic asphalt concrete under the action of short-term cyclic loads and compares them with traditional hot asphalt concrete of types «A» and «B». It is characteristic that crushed stone-mastic asphalt concrete has a greater number of cycles before failure compared to fine-grained asphalt concrete and has less temperature sensitivity in the temperature range from 20 °C to minus 30 °C. It was established that the complex modification of the structure of crushed stone-mastic asphalt-polymer concrete with a reactive thermoplastic of the Elvaloy-AM brand made it possible to increase the fatigue life under dynamic loading by 1.6 times. It is advisable to install coatings made from mixtures of complex-modified crushed stone-mastic asphalt concrete on road sections where there are predominantly static loads from vehicles: public transport stops, interchanges at one level.
Keywords: crushed-mastic asphalt concrete, fatigue durability, strength, complex modification.
