| 摘 要： | 文章针对半刚性基层强度高,但反射裂缝和温缩裂缝突出的缺点,分析不同的基层模量对土基顶面压应变、面层底部的拉应变、面层内部的最大剪应力的影响,提出了合理的基层模量范围。并通过回弹模量试验,分析了不同水泥剂量对水泥稳定碎石基层结构强度的影响。 |
| 关 键 词： | 水泥稳定碎石 低剂量 基层 |

| Abstract: | In accordance with the disadvantages of semi-rigid base,such as reflection crack and temperature contraction crack protruding,the article analyzes the influence of different base modulus on compression strain on the cover coat top,tensile strain on the cover coat bottom and maximum shear stress in the cover coat,and proposes the proper range of base modulus.Through the modulus of resilience experiment,the article also analyzes the influence of different volume on the structural strength of cement stable macadam. |
| Keywords: | Cement stable macadam Low volume Base |
