The CBR test, slake durability test, compressing test and shearing test of the dry and wet redstone granular soilsamples were respectively carried out in this paper.
The pore water permeability coefficient of unsaturated expansive soil is controlled by suction, cell pressure, dry density and degree of saturation of soilsamples.
