摘 要：研究了玄武岩纤维掺量、橡胶颗粒掺量、水灰比对机场道面混凝土力学及耐久性能的影响，采用功效系数法评价了玄武岩纤维-橡胶机场道面混凝土的综合性能，确定了最佳配合比。结果表明：机场道面混凝土的最佳配合比为玄武岩纤维掺量0.3%、橡胶颗粒掺量10%、水灰比0.32，此时，试件的抗压强度、抗折强度、300次冻融循环后的相对动弹性模量较对照组分别提高了27.5%、19.6%、11.1%，6 h电通量和300次冻融循环后的质量损失率分别降低了33.8%、72.2%。
Abstract: The effects of basalt fiber content, rubber particle content and water-cement ratio on the mechanical properties and durability of airport pavement concrete were studied. The comprehensive performance of basalt fiber-rubber airport pavement concrete was evaluated by using the efficacy coefficient method, and the optimal mix proportion was determined. The results show that the optimal mix proportion for airport pavement concrete is basalt fiber content of 0.3%, rubber particle content of 10%, and water-cement ratio of 0.32. Under the condition, the compressive strength, flexural strength and relative dynamic elastic modulus after 300 freeze-thaw cycles of the specimens are increased by 27.5%, 19.6% and 11.1% compared to the control group, respectively, and the 6 h electrical flux and mass loss rate after 300 freeze-thaw cycles are decreased by 33.8% and 72.2%, respectively.
