This paper describes an investigation to determine elevated temperature and reduced time that would be required for accelerated curing of 2 cohesive Oklahoma soils modified and stabilized with salt and lime and that would produce strength gain and chemical products similar to those obtained by 28-day cure at 80 F and 100 percent humidity. Lime-only treatment data were also collected for comparative purposes. A pilot study at 95 percent humidity and temperatures of 120, 110, 105, and 100 F revealed that a temperature of 105 F best simulated conventional strength time curing conditions. For both soils, at saltlime modification and stabilization treatments, 30 hours of 105-F curing produced equivalent 28-day strength. For lime-only treatment, accelerated curing times varied from 30 hours at modification optimum to 72 hours at stabilization optimum. Differential thermal analysis of conventional-cured and accelerated-cured samples indicated similar mineralogical characteristics existed when equivalent strengths were obtained. A tentative-strength mix design procedure using the technique for accelerated curing is suggested.
