玄武岩纤维SMA-13沥青混合料路用性能试验研究

Experimental Study on Road Performance of Basalt Fiber SMA-13 Asphalt Mixture

为了研究玄武岩纤维长度为6mm、掺量为0.49%以及油石比为5.65%的SMA-13沥青混合料的路用性能,对玄武岩纤维SMA-13沥青混合料分别进行了高温车辙试验、小梁弯曲试验、冻融劈裂试验以及浸水马歇尔试验。结果表明,该组合的玄武岩纤维SMA-13沥青混合料具有良好的低温抗裂性能与水稳定性能,而高温稳定性能相对较弱。

In order to study the road performance of SMA-13 asphalt mixture with basalt fiber length of 6 mm,dosage of 0.49%and oil-stone ratio of 5.65%,the high temperature rutting test,trabecular bending test,freeze-thaw splitting test and immersion Marshall test of basalt fiber SMA-13 asphalt mixture were carried out.The results show that the basalt fiber SMA-13 asphalt mixture has good low temperature crack resistance and water stability,while the high temperature stability is relatively weak.
