Coupled Effect of Hydrated Lime and Glass Waste Fine Stabilizers on the Mechanical Properties of Lateritic Soil

Abstract This study has investigated the coupled effect of hydrated lime (L) and glass-waste fine (GF) stabilizers on the mechanical properties of two different lateritic soil samples (specimens A and B). The stabilizing materials L and GF were mixed together (‘‘LGF’’) at equal percentages of 2%, 4%, and 6% of the mass of the soil samples and thereafter used as the soil stabilizer. Compaction tests, the California Bearing Ratio (CBR) test, and the Unconfined Compressive Strength (UCS) test were conducted to determine the coupled effect of the stabilizing materials. The results obtained show that the maximum dry density (MDD) for the stabilized soils is 1.63kg/m 3 at 2% LGF and 1.70 kg/m3 at 4% LGF versus 1.54kg/m 3 and 1.61kg/m3 for the untreated soil for both samples, respectively. For the CBR, it increases to 62% at 4% LGF and 72% at 6% LGF, while the UCS value after curing for 24 hours increases by 30.60% and 40.63% for samples A and B, respectively.
