Stability of Asphalt Binder and Asphalt Mixture Modified by Polyacrylonitrile Fibers

Abstract:

The research was conducted to evaluate pavement properties of polyacrylonitrile fiber asphalt binder and asphalt mixtures, including high temperature stability of binder and mixture, low temperature crack resistance and water stability of mixture. Moreover, polyacrylonitrile fibers were compared with methyl cellulose in the asphalt binder and asphalt mixtures. The result indicates that polyacrylonitrile fibers may improve clearly the high temperature stability of asphalt binder, and pavement performance of mixtures is enhanced obviously. Also polyacrylonitrile fiber binder and mixtures have better performance than methyl cellulose.
