The mix design and testing procedures outlined in this publication are intended to help ensure the long term strength and durability of lime stabilized soils that specifying agencies, design engineers, and laboratory personnel can use with confidence for soil conditions and environmental exposures throughout the United States. These procedures are based on a series of reports by Dr. Dallas Little that summarize the literature on lime stabilization; describe mix proportioning and testing steps for lime stabilized soil; and present field validation of the procedures — see below. This Tech Brief defines other uses of lime for soil drying or modification, but does not address mix design or testing procedures for these other applications. Construction techniques for lime treatment of soils (drying, modification, and stabilization) are addressed in another NLA publication — see below. (6 pp)
