This paper presents the effects of waste ceramic dust on, liquid limit, plastic limit, plasticity index, compaction characteristics, unconfined compressive strength, California bearing ratio, shear strength parameters and swelling pressure of an expansive soil. The expansive soil collected locally was mixed with ceramic dust from 0 to 30% at an increment of 5%. From the analysis of test results it was found that, liquid limit, plastic limit, plasticity index, optimum moisture content, cohesion and swelling pressure decreased, maximum dry density, unconfined compressive strength, California bearing ratio and angle of internal friction increased with an increase in ceramic dust content. From the economic analysis it was found that, ceramic dust up to 30% can be used in strengthening the subgrade of flexible pavements, to save the cost of construction.
Keywords: Expansive soil, ceramic dust, California bearing ratio, cohesion, swelling pressure.
