Temperature Stability Of Asphalt Mixture And Pavement Design

The phenomenon of heavy-duty traffic appears in recent years, which causes fatigue and rut and so on in bituminous pavement and debases service life and level of pavement. Based on the fatigue test, wheel tracking test and creep test of asphalt mixture in a large-scale of temperature, this paper carry through research on character of fatigue and rut of asphalt mixture. Also combined weather condition, this paper accounts the equivalent temperature of fatigue and rut as well as design parameter under the equivalent temperature of delegate area in shaanxi province. According the research overseas and domestic, this paper brings forward rut limitations and axle load conversion based on rut equivalent. Hereby this paper establishes pavement design methodology based on fatigue and rut, also colligate those into multi-target design system of asphalt pavement.
