摘　　要：基于一种内力传递能力大、局部荷载扩散快的新型抗裂夹层系统——双绞合钢丝加筋网夹层系统,以疲劳破坏理论、断裂力学及弹性层状理论为基础,研究双绞合钢丝加筋网应用于沥青加铺层对抵抗荷载型反射裂缝和温度型反射裂缝及抗车辙的路用性能;通过与未加筋夹层系统、玻纤格栅夹层系统的路用性能对比分析,结果显示,双绞合钢丝加筋网夹层系统防治反射裂缝的效果相对最好,抗车辙性能相对最好;玻纤格栅夹层系统防治反射裂缝的效果其次,未加筋夹层系统防治反射裂缝的效果相对最差。Based on a new type of anti-cracking sandwich system with large internal force transmission capacity and rapid local load spreading,it is the sandwich system of twisted-pair steel wire reinforced network,and using the fatigue failure theory,fracture mechanics and elastic layer theory,the study of the road performances of twisted-pair steel wire reinforced network was done about that the twisted-pair steel wire reinforced network was applied to the road performances of asphalt overlay to resist load-type reflective cracks,temperature-type reflective cracks and rutting.Through comparatively analyzing the road performances of double twisted-pair steel wire reinforced network with those of unreinforced interlayer systems and glass fiber grid interlayer systems,it is found that the sandwich system of twisted-pair steel wire reinforced network have the best road performances,and its anti-rutting performance is relatively best in preventing reflective cracks,the road performances of glass fiber grid sandwich system are better to prevent reflective cracks,and the road performances of unreinforced sandwich system are relatively worse.
