Swelling Behaviour of Expansive Soil Reinforced with Geocell and Jute Fibres
To mitigate the effects of the problem created by expansive soils, a number of mitigation techniques are applied. Sand cushioning, chemical stabilization, belled piers, granular pile anchors, and other techniques are only a few examples. It is also possible to reduce the swelling of expansive soil by stabilizing it with randomly distributed fibres. Geosynthetics such as geocells have been utilized as reinforcement in the construction of structures such as foundations, embankments, retaining walls, highways, and so on. This research article discusses the swelling characteristics of reinforced expansive soil. The swelling characteristics of geocell and jute fibre reinforced expansive soil specimens were investigated using one-dimensional swelling experiments in a CBR mould. The geocell reinforced specimen’s swell potential and swelling pressure dropped until 0.80% fibre content and then increased at 1.60% fibre content. Swell potential and swelling pressure reduced as fibre length increased, but only until 40 mm, after which they increased for fibre lengths of 50 and 60 mm. The rate of swelling confirms the above observation. In comparison with the unreinforced specimen, the swelling behaviour of geocell–jute fibre reinforced expansive soil specimens improved. The study highlights the use of geocells and jute fibre towards the stabilization of expansive soil.
