摘要：

Road construction often depends on limited natural resources, prompting researchers to explore waste reuse for eco-efficient solutions. The effects of lime mud (LM), a residue from the cellulose industry, on the stabilisation of different soil types have not been previously studied. The influence of curing period on different geotechnical properties of soil-LM mixtures remains unknown. Their resilient behaviour and plastic deformations were not investigated in previous works. This study addresses these gaps by evaluating the mechanical behaviour of different soils with varying LM contents and subjected to different curing times. Uniaxial Compressive Strength (UCS), California Bearing Ratio (CBR), swelling, resilient modulus, and plastic strain were determined. Results showed that LM improved UCS, reduced swelling, enhanced resilient behaviour, and decreased soil deformability. Structural analyses explained the mechanical performance of asphalt pavements incorporating the soil-LM mixtures. Therefore, LM from the cellulose industry can be a promising alternative for sustainable road construction.
