This paper investigated into the application of fiber-enhanced asphalt mixture in surface layer of the large longitudinal slope pavement of Xi-Sang Highway. Asphalt mixture with and without polyester fiber were used. Focus is on resistance of deformation at high temperature and flexibility at low temperature. Fiber-enhanced asphalt mixture with dynamic stability above 7000 passes/mm indicated excellent rutting resistance. The high temperature dynamic modulus of fiber-enhanced asphalt mixture was much higher than conventional SBS modified asphalt mixture. Three-point blending test result indicated that the maximum flexural strain of fiber-enhance asphalt mixture reached 4180μm/m. It was concluded that fiber-enhanced asphalt mixture was suit to be used in surface layer of the large longitudinal slope pavement of Xi-Sang Highway.

The modification mechanism and high temperature deformation law are obtained by the rutting test of the same matrix asphalt and aggregate gradation with different natural asphalt mixture. It proves that the anti-rutting performance of the asphalt mixture with Iran rock is close to that of SBS modified asphalt mixture.
