THE USE OF LIME-SOIL STABILIZATION AS A CONSTRUCTION EXPEDIENT
The early strength deformation properties of 'uncured' lime-soil mixtures, and of the natural soils were investigated. Based on the literature pertaining to early strength effects of lime-soil stabilization and the laboratory investigation of this study it was found that a substantial gain in stability is realized by the addition of lime to a fine-grained cohesive soil. This gain in stability is reflected by the combined immediate gain in modulus of deformation and shear strength of the 'uncured' lime-soil mixtures. This gain in stability can be attributed to the immediate cation exchange, and flocculation and agglomeration processes that take place when lime is mixed with a fine-grained cohesive soil. The laboratory results were further considered in developing a correlation of the cone penetrometer test results to shear strengths and to moduli of deformation. (Author)
