| 摘 要： | 针对目前水泥稳定碎石基层不同成型方式导致层问不同接触与黏结情况,研究了在这些条件下水泥稳定碎石上下基层层间剪切力大小,以及水泥稳定碎石梁式试件抗弯拉强度.结果表明:与层间铺洒水泥浆和直接分层成型试件相比,一次成型试件抗剪强度大大增加;分层成型和界面受到污染试件与一次成型试件比较,试件整体性下降,弯拉强度降低.

| Abstract: | Aiming at the current condition that different mold methods of the cement stabilized gravel lead to different contacts and bonding conditions between layers,the shear stress of cement stabilized gravel between the upper and lower layers are studied under this condition,and the flexural strength of cement stabilized gravel beam specimens is also achieved.Compared with the spray cement slurry between the upper and lower layers as well as the directly layered molding,the shear strength of once-forming layer is... |
