However, reinforcing subgrades with natural geotextiles is found to be more economic and eco-friendly. The usage of this is limited by its short degradation time period in soil, and to overcome this, researchers started using treated geotextiles. In this study, a systematic lab investigation has been made to understand the behavior of subgrade strength of roads reinforced with alkali activated binder (AAB) treated jute geotextile. Unreinforced soils, untreated and treated jute reinforced soils are tested for CBR, bearing capacity, and the results showed a considerable increase of CBR, bearing values in treated jute geotextiles.Durability tests such as soil burial tests and tensile strengths of degraded JGT are also carried to study the increase in life expectancy of AAB treated jute geotextile. Alkali activated binder improves life expectancy and mechanical properties of jute,and therefore, treated jute geotextile may be used as alternative material for subgrade soil reinforcement applications. 收起
