在原材料和配合比设计基础上,进行SMA-13沥青混合料的马歇尔试验、高温车辙试验、低温弯曲试验、水稳定性试验及析漏飞散试验,对木质纤维和3种矿质纤维在不同掺量下SMA-13路用性能进行了横向对比。研究结果表明:掺加木质纤维的SMA-13沥青混合料吸油效果和路用性能最好;针对文中选用的矿质2号、矿质3号和矿质4号3种矿质纤维,3号矿质纤维的吸油性和路用性能较好。
On the basis of the design of the raw materials and mix ratio,Marshall test,rutting test at high temperature,low temperature bending test,water stability test and analysis flying leakage test about the SMA-13asphalt mixture are conducted.The SMA-13road performance of wood fiber and three kinds of mineral fiber under the different content are compared.The results show that the oil absorbing effect and road performance of SMA-13asphalt mixture mixed with wood fiber is the best;in terms of mineral fiber 2,mineral fiber 3and mineral fiber 4,the oil absorbing effect and road performance of mineral fiber 3is better.
