Abstract
Soil is one of nature's most abundant building resources, starting at the bottom. Almost all types of construction use the soil or are built upon it. Subgrade soil's strength and importance to a road's pavement are unquestionable. Stabilisation is typically required if the soil's strength is low. In order to increase strength, subgrade is occasionally stabilised or replaced with stronger soil material. When the subgrade is comprised of brittle soil, this stabilisation is also appropriate. A reduction in the structural thickness of a pavement may result from an increase in subgrade strength. For soil stabilisation, materials like cement, fly ash, lime, and fibres are frequently utilised. The major goal of this experimental investigation is to add bitumen emulsion to the gravel soil to improve its qualities. It has been attempted to utilise emulsion to increase the CBR values of gravel soil in an effort to increase strength, which could prove to be cost-effective. In this study, the basic characteristics of soil and its strength in terms of CBR are the focus of all laboratory work. a small amount of cement was applied to improve soil stability. Excellent soil strength is seen to come from employing cationic bitumen emulsion (CMS) with a small amount of cement utilised as filler. The best circumstances for combining gravelly soil with CMS First attempts were made with bitumen emulsion. Choosing four specific material conditions to display comes next.
