Effects of Fibre Additive on the High Temperature Property of Asphalt Binder

Keywords： fibre

Polyester fibre and floc xylogen fibre were used to prepare fibre-asphalt binder.An SHRP's dynamic shear rheometer (DSR) was employed to investigate the rheology charac teristics of fibre-asphalt binder, andthe flow resistance of binder was revealed by combining the rutting parameter, G * / sinδ.The results indicate that both kinds of fibres remarkably improved the high temperature pe~orrnance of asphalt binder.At the same time, the reinforcement mechanism of the fibres in the asphalt binder was also analyzed.
