Abstract:: According to the characteristics of polymer fiber modified Superpave mixture, through the Marshall test, water stability and high temperature dynamic stability test of Superpave asphalt mixture modified with different amounts of polyester fiber, comprehensive engineering economy, the appropriate fiber dose was determined to be 1.5‰. Polyester modified Superpave mixtures are suitable for paving in old road coverings. Finally, a reasonable construction process is proposed; The water permeability test shows that this kind of mixture should strengthen the construction compaction.
