| 摘 要： | 通过不同龄期的无侧限抗压强度、劈裂强度、抗压回弹模量及温缩等试验,研究了3种典型级配类型对水泥稳定碎石路用性能的影响。结果表明:骨架结构对早期强度起主要作用,结构密实性对后期强度影响较大;骨架结构越好,抗变形能力越强,长期抗压回弹模量越大;填料含量越多,温缩系数大,填料含量少,则温缩系数小。

| Abstract: | Through test on unconfined compressive strength,splitting strength,compression resilience modulus and temperature contraction at different ages,this paper studies the influence of 3 typical graded cement stabilized gravel on pavement performance.The result indicates that framework structure has a major effect in early strength;structure compaction has greater influence on later strength;better framework structure will lead to stronger deformation resistance and greater long-term compression resilience modul... |
