Abstract

Abstract

In order to investigate the viscoelastic performance of fiber reinforced asphalt concrete, five kinds of cylinder samples were produced, and four samples for each cylinder sample were tested on MTS810 by using uniaxial static compression creep test at 45 ℃.The viscoelastic performance was simulated by using four-unit five-parameter model, its parameters were obtained from the data of the test, and a four-unit five-parameter viscoelastic constitutive model with fiber content was set up.The loading process of the test was simulated by using the new model, and the influence of fiber content on the performance was analyzed.Analysis result shows that the creep response of fiber reinforced asphalt concrete is similar to that of conventional asphalt concrete except the difference of creep deformation, the computation optimal average value of fiber content is 0.18%, its test optimal value is 0.20%, the difference between the values is less, so the new model may be applied in the reference of theory research and material design.
