The indoor geotechnical test was carried out on the full-strong weathered sandy slate. The compaction parameters, gradation composition, and liquid-plastic limit were analyzed to determine whether the undisturbed soil was suitable for the filling of highway subgrade. The main performance indexes of cement improvers were studied. The liquid plasticity index of cement-modified whole-strong weathered sandy slate was studied different ash-added amount. Through direct shear test, the amount of ash added and the presence or absence of confinement were considered. The effect of conditions on the strength of cement-modified full-strong weathered sandy slate was studied.
