摘要
为了探讨路面结构层中加入纤维格栅后的疲劳特性，就ＡＣ１３Ｉ型的细粒式沥青混合料加网与不加网２种情况进行了疲劳对比试验，分析了试验结果，得出了加网与不加网混合料的疲劳方程以及加网后同等应力水平下混合料疲劳寿命提高６倍的结论．
Mixed pitch AC13I was carried out alternating bending contrast test in order to discuss alternating bending function of fiber grilwork in road structure.Test result and preliminary conclusion were as followed:alternating bending equation of latticed mixed material and mixed material without lattice.Alternating bending life of latticed mixed material rised 6 times under the same stress level.
