The invention provides an asphalt pavement anti-rut performance simulation method considering load and high-temperature interval, using finite element software, which comprises the following steps: selecting a pavement structure and a material; establishing a rut estimation model; selecting a material parameter and a mechanical constitutive model; obtaining meteorological data and traffic daily distribution; simplifying a load action mode; determining load action time and interval time; determining a high-temperature period interval; simulating a temperature field; estimating a pavement rut; and judging the anti-rut capability of the pavement structure. According to the method, the characteristic that the asphalt pavement automatically recovers partial deformation at the load action interval and the high-temperature period interval is considered so that the rut simulation is closer to the real condition and the problem of large simulation result error of the existing method is solved;meanwhile, the anti-rut performance of the specific pavement structure can be judged, that is, a pavement structure with better anti-rut performance is selected through a virtual test without the needfor carrying out comparison experiments through constructing a test road, thus saving significant cost.
