Influence of Graduation on Road Performance of Fibers-Reinforced Asphalt Pavement

Abstract:

Rutting test, residual stability test and freeze-thaw split test were used to measure the properties of asphalt mixture with different graduation and same mixing amount of fibers, the results were analyzed to obtain the influence of graduation types in the road performance of fiber-reinforced asphalt mixture. The results showed as follows: fibers could obvious improve the high temperature property and water stability of asphalt mixture; the graduation types have visible impact on the improvement of all properties of fibers-reinforced asphalt mixture; SMA-13 has the greatest influence in improving the performance of fibers-reinforced mixture; the improving effect of dense graduation AC mixture will gradually decrease when the nominal maximum aggregate size was becoming bigger; graduation optimization design should be used in mix design of fibers-reinforced mixture to enhance its road performance.
