Abstract:
A method is shown for reducing the adverse swelling action of sulfates in clay bearing soils during lime stabilization by treating soils having high sulfate content with a soluble aluminum compound that can react with the sulfate ions in the soil to form ettringite or other swelling species during the initial reaction with lime stabilization prior to compaction and paving of the lime treated soil. The amount of soluble aluminum ions added to the soil is determined by the concentration of sulfate in the soil and the other soil parameters such as the soils PI, clay type, etc.

Claim (Index 7):
An improved method for reducing the adverse delayed swelling action of soluble sulfates present in clay bearing soils comprising the steps of: first, the addition of a soluble aluminum ion compound into the soils in an amount effective to rapidly react with soluble sulfates present in the soils with the further addition of calcium hydroxide ions added to the soil by the process of lime stabilization which with this addition of soluble aluminum ions and soluble calcium ions to the sulfate containing soil will immediately start the formation of ettringite and/or other swelling calcium alumina sulfate hydrate species prior to the compaction and pavement of the soil and thus eliminated the adverse delayed sulfate swelling of the compacted soil.
