Current Advances in Civil Engineering Research (Volume - 3), edited by Dr. N. Sudharsan, presents four cutting-edge chapters highlighting modern experimental and computational approaches to soil stabilization, project scheduling, structural reliability, and lightweight eco-concretes. The volume includes research on improving expansive soils using crumb rubber and lime, time-cost trade-off comparisons between project crashing and linear programming methods, the application of reliability theory to soil variability, and the behavior of lightweight concrete beams using expanded clay and waste plastic. These chapters integrate sustainable materials with advanced project management and geotechnical modeling techniques. The volume serves as a valuable reference for civil engineers, researchers, students, and construction planners interested in blending environmental responsibility with technical innovation in geotechnical and structural engineering.
