A method and composition for reducing the swelling capacity of clay-containing soil, thus lowering volume change in soil, and thus enhancing the stability of soil, particularly expansive clay soil, in order that it is sufficiently stable, such that roads, pavements and some types of buildings ...
The depth of burrowing and soil mixing is commonly delineated by both a rapid change in color (from dark humus-rich A horizons to oxidized B horizons) and the presence of a stone or gravel layer at the base of the mixing zone (Figure 7). The increase in clay with time decreases ...
