Abstract
Calcium carbide residue, a byproduct of acetylene gas production, has gained attention as a potential soil stabilizer for soft highway subgrades. This residue contains a high concentration of calcium hydroxide (Ca (OH)2), which exhibits excellent pozzolanic properties, making it a suitable candidate for enhancing the engineering properties of weak subgrade soils. Laboratory investigations and field evaluations are crucial steps in assessing the feasibility and effectiveness of using calcium carbide residue for subgrade soil improvement. Soft subgrade soils in highway construction often pose challenges, including low bearing capacity, poor load-bearing ability, and susceptibility to settlement, which can lead to increased maintenance costs and safety risks. Researchers and engineers have been exploring various soil stabilization methods to address these issues. The quality of subgrade soils is crucial for the durability and performance of highway networks. Many regions require cost-effective methods to enhance soft subgrade soils to extend the service life of road infrastructure.
