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 9):
The method of  claim 7 , where the improved method for eliminating the adverse swell potential of stabilized sulfate soils is based on the rapid formation of the swelling ettringite before the calcium hydroxide can solubilize the aluminum ions from the clay aluminosilicate minerals in the soil which is a long term process that can take days, week or months, thus enabling the rapid formation of the swelling calcium aluminum sulfate hydrate compounds the soil can be compacted and paved without the future adverse swelling of the compacted soil/pavement.
