• Abstract:

  The Engineering Characteristics Of Broad Soils, Particularly Black Textiles Soil (BCS), Present Substantial Challenges In Construction For Civil Engineering As A Result Of Their High Plasticity, Low Shear Strength, And Substantial Volume Changes Due To Moisture Fluctuations. Researchers Have Increasingly Concentrated On Environmentally Conscious And Cost-effective Stabilisation Techniques That Utilise Agricultural And Industrial Refuse In Order To Address These Constraints And Advance Sustainable Development. This Review Investigates The Potential Of Ash From Sugarcane Bagasse (SBA) And Low-density Polyethylene, Or LDPE, Waste Plastic As Partial Substitutes And Additives To Enhance The Geotechnical Features Of BCS At The Subgrade Level. Sugarcane Bagasse, A Plentiful Byproduct Of The Sugar Sector, Possesses Pozzolanic Properties That Increase Soil Strength And Decrease Plasticity. Simultaneously, LDPE Waste Plastic, A Major Pollutant, When Shredded And Blended With Soil, Contributes To Increased Ductility And Load-bearing Capacity Due To Its Tensile Resistance. The Combined Application Of SBA And LDPE Provides A Dual Benefit—mitigating Waste Disposal Problems While Enhancing Soil Performance.This Paper Conducts A Systematic Review Of Previous Research, Experimental Methods, And Real-world Applications That Examine Changes In Features Such As California Burden Ratio (CBR), Unconstrained Compressive Strength (UCS), Boundaries Of Atterberg, And Swelling Behaviour. The Review Suggests That The Optimal Concentrations Of LDPE Plastic (0.5–2%) And The Ash From Bagasse (typically 5–10%) Lead To Substantial Enhancements In Subgrade Stability.The Findings Support The Integration Of Agro-industrial Waste In Pavement Subgrade Treatment, Aligning With Environmental Sustainability And Circular Economy Goals. Further Research Is Suggested For Long-term Performance Analysis Under Varying Climatic And Traffic Conditions.
