摘要
Fatigue crack is one of the main road damage forms of asphalt pavement structure, and serious impact the asphalt pavement performance and service life. Asphalt mixture has typical viscoelastic,and can get Burgers model and viscoelastic parameters form creep test. Using finite element method of fracture mechanics, simulation under dynamic loading, research crack extending behavior of common asphalt concrete pavement and mixed with 0.2% of sisal fiber asphalt concrete pavement. From the results, it can find out that when mixed with sisal fiber, the anti-fatigue cracking performance is obvious enhancement.
