Study on Fatigue Performance of Rubber Asphalt Stress Absorbing Interiayer

With widely using of semi-rigid base asphalt pavement in China,reflective crack has become a big problem in asphalt pavement. At present,a effective solving method is using stress absorbing anti-cracking interlayer.Stress absorbing interlayer should balance fatigue performance,high-temp performance and interface shearing strength of the asphalt mixture.Rubber asphalt mixture has been domontrated excellent high-temp perfomance and shearing strength,this paper focus on the fatigue performance and its key factor. These will give referrence to enhance the fatigure performance of rubber asphalt mixture and widely application in future.
