玄武岩纤维和聚酯纤维对OGFC-13路用性能研究
|
摘要
为了改善OGFC-13的路用性能,减少路面早期病害的发生,采用车辙试验、冻融劈裂试验、劈裂试验和表面构造深度试验,来研究玄武岩纤维和聚酯纤维对OGFC-13高温稳定性、水稳定性、低温抗裂性和抗滑性的影响,并对其作用机理进行分析。试验结果表明:与不添加纤维相比,玄武岩纤维和聚酯纤维的添加均可以改善OGFC-13的高温稳定性、水稳定性能和低温抗裂性,但降低了OGFC-13表面构造深度,削弱其抗滑性。聚酯纤维对OGFC-13路用性能的作用效果均优于玄武岩纤维。
In order to improve the road performance of OGFC-13 and reduce the occurrence of early pavement diseases, this paper studied the effects of basalt fiber and polyester fiber on OGFC-13 high temperature stability, water stability, low temperature crack resistance and slip resistance by rutting test, freeze-thaw splitting test, splitting test and structure depth test, and its mechanism was analyzed. The results show that the addition of basalt fiber and polyester fiber improved the high temperature stability, water stability and low temperature crack resistance of OGFC-13 compared with no additive, but the decrease the structure depth and weaken its slip resistance. The effect of polyester fiber on the performance of OGFC-13 was better than that of basalt fiber.
