Lignin fiber, basalt mineral fiber (abbreviated as mineral fiber) and polyester fiber are being used for Stone Matrix Asphalt (SMA) pavement in China. However, there is not sufficient information available for the selection of these three fibers with regard to different applications of SMA pavement. In order to investigate the effects of these three fibers, SMA-16 is used as an example in this study using these three different fibers. Based on the Marshall test, Residential stability test,

The results show that the fibers significantly improved the high temperature stability and water stability of the mixture. The influence of different fibers on high temperature and water stability of the SMA mixture are not very significant. Of the three SMA mixtures, each with different fibers, SMA mixtures with mineral fibers exhibit optimal high temperature and water stability.
