Study of the Plasticity Coefficient of Asphalt Concrete
Abstract: The destruction of asphalt concrete coatings during operation makes us think about the possibility of bringing the physical and mechanical properties of asphalt concrete in order to increase the service life of road clothes. Asphalt concrete mix consists of mineral materials (gravel or crushed stone, natural or crushed sand, mineral powder) and organic binder (bitumen). The correctly selected composition of the asphalt concrete mixture allows the asphalt concrete in the road surface to provide the specified values of bending strength, shear modulus of elasticity, resistance to water (water resistance), ensure chemical resistance, and ensure the workability of the mixture. Unsatisfactory indicators of the quality of asphalt concrete in the road surface during long-term operation include changes in rheological properties from temperature changes, from plastic to brittle, bitumen aging (changes in physico-chemical bonds, a decrease in the thickness of the bitumen film on mineral particles). Therefore, it is necessary to pay comprehensive attention to the study of the properties of asphalt concrete mixture and asphalt concrete.
Keywords: asphalt concrete mixture, asphalt concrete, bitumen, rheological properties, plasticity, elasticity.
