Investigation of High Temperature Properties of Asphalt Mixture Containing Fibers

Fibers are extensively used in civil engineering applications for many years. The fibers provide three-dimensional reinforcement of the mixture. The main objective of paper is to evaluate effect of fibers on performances of asphalt mixture at high temperature. Three different fibers were used as modifiers: polypropylene fiber, polyester fiber and cellulose fibers. A SHRP's Dynamic-Shear-Rheometer (DSR) was employed to investigate the rheology property of asphalt-fiber mortar. The wheel tracking device was employed to evaluate rutting resistance of asphalt mixture. The strengthening mechanism in fiber-reinforced asphalt mixture was studied. DSR test results demonstrated that fiber asphalt mortar showed remarkable improvement of properties in comparison with the control asphalt mortar. The wheel tracking test results showed that fiber performed different performance level but showed more resistance to permanent deformation according to the fiber type and fiber contents.
