ABSTRACT
In this paper test results of hot fine-grained asphalt concrete samples on creep by the direct tensile scheme at temperature of 20±2°C and stress from 0.04 to 0.24 MPa are presented. It is shown that the asphalt concrete creep curve has three characteristic sites. On the first site creep strain is described by the integral equation of Boltzmann-Volterra with the Abel’s creep kernel. The kernel parameters determining method is given. On the second site the creep curve is described by the straight line equation and characterized by the strain rate which is a power function of stress. The creep curve sites durations and the asphalt concrete long-term strength have been defined. The creep curve sites durations and the asphalt concrete failure time depend on stress. Stress influence degree is such that stress change on one order causes their change more than three orders.
