摘要
探讨了玻璃纤维及其与钢纤维、玄武岩纤维组合对高速公路沥青混合料路用性能的影响,重点评估了纤维类型和掺量对沥青混合料黏结性、高温稳定性、低温性能、中温抗裂性能和水稳定性的综合作用。结果表明,玻璃纤维改性沥青混合料在所有性能测试中均表现最佳,特别是当质量分数为0.3%时,其黏结强度最高达到1.8MPa。玻璃纤维与钢纤维的混合使用进一步增强了混合料性能,尤其在高温稳定性方面,马歇尔稳定度达到18kN,显著高于单一纤维使用。
The influence of glass fiber and its combination of steel fiber and basalt fiber on highway asphalt mixed material roads was explored.The experiment focuses on the comprehensive effect of fiber type and blending on asphalt mixture,high temperature stability,low temperature performance,medium temperature crack resistance,and water stability.The results show that glass fiber modified asphalt mixture performed the best in all performance tests,especially when the mass fraction was 0.3%,its adhesive strength reaches 1.8 MPa.The mixed use of glass fiber and steel fibers further enhances the performance of the mixture.Especially in terms of high temperature stability,Marshall stability has reached 18 kN,which is significantly higher than the use of a single fiber.
