Influence of Fiber Type on Road Performance of Stone Mastic Asphalt
Stone Matrix Asphalt (SMA) is a gap-graded mix that is gaining popularity worldwide. Various types of fibers are used as additions in SMA asphalt mixture. However, there is not sufficient information available for the selection of different fibers with regard to different applications of SMA pavement. In this paper, SMA-13 using three different fibers: lignin fiber, polyester fiber and basalt mineral fiber, is used as an example. Based on the Marshall test, Schellenberg Binder Drainage test, Cantabro test, Residential stability test, Freezethaw cycle test, Rutting test and Bending test of small beam of the mixtures, the influences of different fibers on road performance of SMA mixture were investigated. The results show that SMA-13 mixtures using mineral fibers exhibit optimal high temperature and low temperature stability; while SMA mixtures using lignin fibers exhibit optimal water stability.
