The objectives of this study were to evaluate the feasibility of lime treatment as an alternative design and remedial method for restoration of shallow surface slides, and furnish criteria for mix design, design parameters, and construction procedures. The lime treatment susceptibility of four typical levee slide clays in the Lower Mississippi Valley Division was evaluated by mix design procedures using pH tests and evaluating effects of normal and accelerated (105 F) curing times, immersion, density and water content, and compaction delay on unconfined compression test (UCT) strengths. A mix design procedure for assessing the feasibility of using lime for levee slide restoration was developed. The procedure recommends a 28-day normal average UCT-strength increase of 3.6 tsf and a 24-hr immersion strength of 2.12 tsf at optimum conditions as stabilization criteria where strength and durability are critical. Where only soil modification is desired a minimum plasticity index reduction of 50 percent is deemed acceptable, with 28-day strength increases of 100 percent for semicompaction conditions as an optional criteria for judging lime treatment feasibility.
