In India, nearly 23% of land surface is covered with expansive soil. The problems associated with such soils caused the tremendous cost to the project if proper geo-technical investigation and stabilization are not done. To prevent the failures of structures like foundations, retaining structures, slopes, lightweight structures, pavements, the improvement of swelling soil should be done which is economical and environmentally friendly. The use of lignin-based organic polymer which is a by-product of pulp industry is a sustainable and viable technique. An assessment of lignosulfonate as a stabilizer is necessary, and thus in the current study, the compaction, plasticity, swelling, and strength characteristics of expansive soil are checked with addition of sodium lignosulfonate in percentages varying from 0 to 12. The plasticity characteristics of expansive soil are seen to be improved significantly. However, a marginal increase in strength occurs with the addition of lignosulfonate which further increases with curing period.
