Reduction of Sulfate Swell in Expansive Clay Subgrades in the Dallas District
There are three purposes for stabilizing the natural soil in place beneath pavements: (1) to provide a working table for construction equipment during wet weather; (2) to reduce the roughness due to an expansive clay subgrade; and (3) to provide a permanent layer in the pavement structure that is stiffer than the natural soil. No stabilized layer only 0.2 m (8 in) thick will reduce expansive clay roughness very much. This report shows that there are non-calcium stabilizers that will serve successfully as a working table (Purpose No. 1) but the study did not and could not determine the permanence of the treatment (Purpose No. 3). That determination must await the results of monitored pavement test sections.
