The results of an experimental study of changes in the physical and mechanical properties of modified asphalt concrete after long-term exposure to high temperature are presented. When studying of aging processes modified by adding still residues of chemical production of asphalt concretes with the waste of crushing local low-strength limestones, a new technique is proposed that makes it possible to track the aging processes of experimental samples using a dimensionless indicator – coefficients of aging and intensity. The nature of the change in values of property indicators over time during heating at a high temperature (150oC) for 0–7 hours, expressed as an indicator of the intensity of aging, shows the comparative stability of materials over time, i.e. their stability in extreme conditions. Under the influence of high temperature, the group composition of petroleum bitumen changes rapidly, which leads to a decrease in its adhesive ability and, accordingly, asphalt concretes with their use. There is a need to predict these processes. Due to the fact that until recently there is no unified methodology for evaluating the aging processes of asphalt concrete, the staff of Volga State University proposed to evaluate the comparative durability of the materials under study by the rate of change of individual indicators using the aging coefficient and the intensity of aging.
