Evaluation of Admixture Stabilization for Problem Laterite
Publication: Journal of Transportation Engineering
Volume 115, Issue 6
Abstract
The paper presents results of research carried out to evolve suitable evaluation criteria for admixture stabilization for problem laterite where Portland cement is used as the stabilizer and hydrated lime as the admixture. The results presented show that there are promises of increased strength gain with time. In addition, high durability is recorded for the range of mixes tested. Accordingly, unconfined compressive strength (UCS) and California bearing ratio (CBR) values of and 90%, respectively, are recommended as evaluation criteria for this form of stabilization for problem laterite. This high value of UCS compared with the conventional value of for lime stabilization is justified by the superior pozzolanic nature of the cementitious reaction in this admixture stabilization.
