【摘要】：為研究不同纖維對SMA(Stone Matrix Asphalt)的適用性,選取木質(zhì)素纖維和玄武巖纖維,通過馬歇爾方法得出不同纖維SMA的最佳油石比,并分析不同纖維SMA的性能。結(jié)果表明:在相同空隙率下,玄武巖纖維SMA的最佳油石比較小,謝倫堡析漏損失量較大,肯塔堡飛散損失量較小,其低溫抗裂性和抗疲勞性能均大幅優(yōu)于木質(zhì)素纖維SMA,其水穩(wěn)定性略優(yōu)于木質(zhì)素纖維SMA,60℃和70℃下的車轍試驗結(jié)果表明:玄武巖纖維SMA的高溫穩(wěn)定性更好,并且溫度越高,其高溫性能越顯著。
[Abstract]:In order to study the applicability of different fibers to SMA (Stone Matrix Asphalt), lignin fiber and basalt fiber were selected, and the optimum ratio of oil to stone for different fiber SMA was obtained by Marshall method, and the properties of different fiber SMA were analyzed. The results show that under the same porosity, the optimum SMA of basalt fiber is smaller, the leakage loss of Schelenburg is larger, and the loss of Kentucky Flying is smaller. The low temperature cracking resistance and fatigue resistance of basalt fiber SMA are both significantly better than those of lignin fiber SMA,. The results of rutting test at SMA,60 鈩，
