Tensional Ability of Basalt Fiber Enforced Asphalt Mixture

Tensional ability of basalt fiber enforced asphalt mixture studied by split tensile test then compare with the normal asphalt mixture. The tensional ability is increasing while increase the basalt fiber percents. The tensional strength increase 3.5%, 7.8%, 3.5% and the failure stiffness modulus increase 15.1%, 40.4%, 11.8% while the added basalt fiber is 0.15%, 0.2%, 0.25%, respectively. The result shows that basalt fiber can enhance the tensional ability of asphalt mixture significantly, and the optimum percents of basalt fiber is 0.2%.
