Abstract

Abstract

In order to study the deformation of polyester fiber asphalt concrete with different fiber contents by splitting test, Marshall samples of asphalt mixture, with fiber quality contents of 0, 0.15%, 0.20%, 0.25% and 0.30%, were tested by MTS810 at (15 ℃, ) a non-dimensional toughness index was induced in order to evaluate the deformation performance of polyester fiber asphalt concrete.It is found that polyester fiber doesn't evidently change the splitting strength, but it significantly enhances the toughness and deformation resistance of asphalt concrete, the proposed toughness index can properly evaluate the deformation resistance of polyester fiber asphalt concrete, and the optimum fiber content is about 0.20% according to the toughness index and the splitting strength.
