格栅沥青混凝土性能研究

The Performance Research of Asphalt Concrete Reinforced with Grid

通过弯曲试验和车辙试验，对材料与级配相同情况下不同加筋方式的格栅沥青混凝土的弯曲破坏性能和抗车辙能力进行了研究。从弯曲破坏过程的不同及裂缝尖端受力状况的改变，揭示了沥青混凝土中加入格栅可抑制裂缝向上发展的机理；由沥青混合料车辙形成过程，分析了格栅沥青混凝土抗车辙能力提高的原因。

This paper engages in research on bending failure characteristic and resistance to rutting of grid asphalt concrete with the same material and gradation but different reinforcement pattern by bending test and rutting test. From the difference of bending failure process and the change of bearing state of crack tip, this paper reveals the reason of controling crack expanding of asphalt concrete reinforced with grid. According to forming of asphalt mixture, the stability improvement of asphalt concrete with adding grid is analysed.
