Abstract

This paper was to study the effect of common salt on the compaction and California Bearing Ratio (CBR) properties of eggshell stabilized lateritic soils with a view to discovering a good compliment for eggshell as a useful stabilizer for road works. Classification and consistency tests were performed on the soil samples which were also subjected to compaction and CBR tests. Stabilization was performed at optimum eggshell and with 2, 4, 6, 8, and 10% of common salt. The addition of common salt reduced the Plastic Indices (PI) of the samples. The values reduced from 8.041, 7.604 and 6.828% to 8.031, 1.247 and 1.233% respectively in samples A, B and C. Maximum Dry Density (MDD) increased from 2137 to 2080 kg/m3 and 1977 to 2070 kg/m3 in samples A and C respectively. The unsoaked CBR values also increased from 34.78 to 50.99 kN/m2, 15.64 to 28.89 kN/m2 and 27.31 to 34.20 kN/m2 respectively in samples A, B and C. The result showed that the addition of common salt improved the compaction and CBR characteristics of eggshell stabilized soils.
