Review on Bitumen Emulsion Used in Gravel Road Stabilization

Authors- Veerendra K Shama, Hariram Sahu

Abstract-This study explores the enhancement of gravel soil strength through stabilization using cationic bitumen emulsion (CMS), focusing on its application as subgrade material in road pavements. Traditional stabilizers like cement, lime, and fly ash can be costly or inaccessible, making CMS a potential alternative. Laboratory tests assess the effects of CMS and small cement additions on California Bearing Ratio (CBR) values, dry density, compaction efforts, and curing times. Findings reveal that the combination of CMS and cement significantly improves soil strength, enabling reduced pavement thickness. This method offers a cost-effective and sustainable approach to soil stabilization, particularly in regions with limited access to conventional stabilizers.
