Research to Performance of Basalt Fibre Strengthen SBS Modified Asphalt Mixture

摘要

This paper made a research into each performance index of basalt fibre strengthen SBS modified asphalt mixture by using two kinds of gradation, which are AC-20C of mid-surface and AC-13C of upper layer. And compared and analyzed with the same gradation of carbon fiber strengthen SBS modified asphalt mixture. The results showed that compared to carbon fiber strengthen SBS modified asphalt mixture Conbasalt, basalt fibre strengthen SBS modified asphalt mixture is equivalent on water stability and fatigue resistance, etc. It is relatively weak on low-temperature crack resistance. But it has decided advantage on high temperature stability.
