摘要
现阶段随着交通量及重轴载车辆的日益增加,我国沥青路面的使用寿命逐渐缩短.因此,改善道路的路用性能和使用周期是我们道路工作者研究的重点.玄武岩纤维与常规纤维相比具有韧性好、强度高、密度大、物理化学性质稳定、与沥青混合料具有很好的相容性等优点.通过对掺入0.3%玄武岩纤维的沥青混合料路用性能研究,得出玄武岩纤维的掺入对沥青混合料的高温稳定性、抗水毁性能、低温开裂等性能得到了改善;掺入玄武岩纤维的沥青混合料动稳定度提高1.30倍,残留稳定度提高了1.05倍,冻融劈裂强度比提高了1.05倍.
The service life of asphalt concrete pavement in our country has gradually shortened along with theincreasing of traffic and heavy axle vehicle. Therefore,the road workers focus on the study of improving roadperformance and service cycle. The basalt fiber has the advantages of good toughness,high intensity,high density,stable physicochemical property,and good compatibility with asphalt mixture. This paper studies on the roadperformance of asphalt mixture which mixed with basalt fiber,and analyzes the improvement effect of asphaltmixture with basalt fiber.
