Sustainable assessment and carbon footprint analysis of polysaccharide biopolymer-amended soft soil as an alternate material to canal lining

Kuttanad region in Kerala, India, is a place that predominantly consists of soft soil formations with low shear strength and water resistance rendering them problematic for construction purposes. Pavements constructed on such deposits have been subjected to structural rutting the high erodibility in-situ necessitates need use suitable ground improvement techniques. The present environmental scenario demands implementation sustainable techniques rejuvenation effective stabilizers enhancing engineering properties. This study investigates amelioration using chitosan as amendment improve its durability characteristics. untreated chitosan-treated samples were exposed 5 h wetting cycle followed by 43 drying cycles until their failure. unconfined compressive (UCS) prepared different dosages (0.5, 2, 4%) cured 14, 28, 60, 90 days was evaluated at onset after each measure index. amended 2% withstood five UCS more than 1,000 kPa. drip erosion tests used check performance aforementioned curing periods. 4% resisted entire test duration 10 min indicating highest resistance. findings current through reinforced effectiveness an biopolymer soils constant attack can be easily implemented places vulnerability. A typical earthen canal lining reduced carbon emissions 8.74 7.44 times compared conventional amendments like lime cement Carbon Footprint Analysis.
