研究结果表明，膨胀性泥页岩填料的承载比（CBR）和回弹模量主要受制样含水量及干密度的控制；
The results have shown that the CBR and resilience modulus of expansive shale were mainly controlled by moisture content and dry density.
干密度值较高时，土样处于密实状态，表现出剪胀特性，有效主应力比-应变曲线近于应变软化型；
When the dry density is relatively high, this dense specimen shows shear dilatation characteristics, and the effective principal stress ratio tends to be strain softening phenomenon.
