Viscoelastic Fatigue Damage Properties of Asphalt Mixture with Different Aging Degrees

다국어 초록 (Multilingual Abstract)

In order to reveal the effects of aging on fatigue damage evolution pattern of asphalt mixture, and to reveal the fatigue damagepatterns of asphalt pavement during its service life more accurately, the viscoelastic fatigue damage model for the aged asphaltmixtures was proposed based on the Burgers viscoelastic model. The dissipation energy was taken as the damage variable, and thedirect tension fatigue tests for asphalt mixture in five different aging degrees were conducted. The viscoelastic parameters of the agedasphalt mixtures were obtained.The calculationmethod of the cumulative fatigue damage was proposed, which considers the agingeffects. Moreover, the critical fatigue damage degree and fatigue life calculation equations were derived by employing the fatiguedamage model, which were calculated and compared. The calculation errors range from 3% to 18%, which was within an acceptableerror range of 30%. The research results show that the aging has a prominent impact on fatigue properties of asphalt mixtures, whichcould be illustrated by the change of the parameters of the viscoelastic fatigue damage model for the aged asphalt mixtures. Theprediction precision of fatigue life is acceptable for using the proposed viscoelastic fatigue damage model.
