Effects of Chemical Stabilisation of Eggshells-Lime and Fly-Ash-Cement on the Structural Strength of Subgrade Soil in Rural Roads

Authors: Mohammad Shanawar Khan and Shohel Amin

Abstract: This study examines the chemical compositions of eggshell powder (ESP) and lime as the soil stabilisers and compared with the compositions of cement and fly-ash to understand the optimal distribution of chemical stabilisers maximizing the bearing capacity and structural integrity of subgrade soil. Two chemical compositions of ESP-lime and fly-ash-cement with 2%, 4%, 6% and 8% of total mass of soil sample were mixed with 6% and 4% constant ratio of lime and cement
