POLYNOMIAL MODELS FOR PREDICTING TIME LIMITS FOR COMPACTION AFTER MIXING OPERATION OF LATERITIC SOIL REINFORCED USING CEMENT OR LIME

The demand for natural aggregates has increased in recent years because of diverse environmental interests. Consequently, its cost soared astronomically and the utilization lateritic soil low-cost roads been an attractive option. In most cases during road construction, unprecedented conditions may lead to delays compaction treated after mixing operation placing had taken place. Thus, this study developed polynomial models predicting time limits within 0-180 minutes at 30 intervals reinforced with cement lime. percentage contents by weight dry or quick lime mixed were 2, 4, 6, 8 10%. Consistency indices tests particle size analysis carried out on untreated characterization. conducted prepared test (Standard Proctor), California Bearing Ratio (CBR) unconfined compressive strength (UCS) 7 days curing. AASHTO classification system Unified Soil Classification rated be A-6(13) clayey (CL), respectively. Ordinarily, was found a poor construction therefore requires treatment improve order make it useful pavement purposes. At increase mixing, there reductions characteristics soils that good fit using cement/lime contents, strengthened soil. gave coefficients correlation determination 0.988 0.976, respectively, when whereas, case lime-prepared soil, values 0.966 0.933, optimum moisture content (OMC), CBR UCS (7 curing) entirely statistically significant 95% confidence level.
