Engineering properties of red clay Red clay has poor physical properties such as high void ratio, high water content, high liquid plastic limit and plasticity index, but it has good mechanical properties such as high strength, low compressibility.
Thus, as the areas of red clay are different, there are changes in its strength, deformation properties; main influencing factors are also different.
The existence of fractures, and natural factors and the function of the water, will inevitably affect the long-term strength and stability of the embankment.
