DEVELOPMENT OF SOIL STABILIZATION GUIDELINES FOR ALABAMA SOILS
A comprehensive sampling program of forty-seven surficial Alabama soils was conducted to develop state-wide lime stabilization guidelines. The selected soils were mixed with six percent hydrated lime, compacted into Harvard miniature-sized specimens, cured in a sealed condition for forty-eight hours at 120 deg. F, and tested to determine their unconfined compressive strength of Harvard miniature soil specimens prepared in an identical manner with the exception that hydrated lime was not added. The lime reactivity of the soil was determined using the Thompson criteria that the unconfined compressive strength difference between the lime-treated and untreated soils must be greater than or equal to fifty psi. A statistical "t" test of hypothesis was used to estimate the reliability of the results. A color-coded lime-reactivity state surficial soils map was prepared to assist civil engineers in assessing soil stabilization alternatives. /Author/
