SYNTHETIC FIBERS IN ASPHALT PAVING MIXTURES. FINAL REPORT

Laboratory and field tests were performed to evaluate eight types of chopped synthetic fibers as additives to reduce cracking in hot mixed asphalt concrete. Laboratory tests included Hveem and Marshall stability, resilient modulus, indirect tension, flexural and tensile fatigue, creep and resistance to moisture damage. Thin overlays were placed in East and Wst Texas and observed for periods of one and two years. respectively. Laboratory tests showed that fibers added flexibility to a paving mixture and improved resistance to crack propagation; however, they also increased compaction requirements. There was no significant difference in the performance of any of the eight different fibers. Based on review of literature and early field performance data, the cost effectiveness of fibers as an additive to reduce cracking in asphalt paving mixtures appears questionable. (Author)
