Abstract: The improvement of any nation depends on accessibility and interconnectivity to distinctive places via well connected transportation network. Road transportation is the most adaptable mode of transport under various prerequisites of topography and therefore top priority is given to enhance avenue transportation amenities all through the world by allocating large capital investments. About 40% of total land in India is blanketed by clayey soils and inevitably the roads have to pass via such sub grades. Generally, flexible pavements are favored to rigid pavements due to less preliminary cost, smooth driving surface and convenient maintenance. The design pavement thickness over clay sub grades is large due to their low soaked CBR values and so the execution cost is high. In spite of imparting large pavement thickness, common debacles noticeable in flexible pavements over clayey soils are immoderate rutting, wavy surface, longitudinal cracking alongside wheel track and shear failure in edge region. Further, expansive clays pose serious issues to construction of pavements due to their shrink-swell behaviour with moisture fluctuations and also make pavement construction steeply-priced due to their very low strength in saturated condition ensuing from swelling. Efforts are being made via researchers from time to time to enhance the strength and stability of the clay sub grades in regular and expansive soils in specific via stabilization, reinforcing, moisture manipulation and soil substitution techniques. The advent of geo synthetics has drawn the interest of motorway engineers to contemplate them for use in pavement development to enhance performance. Particularly, geo-synthetics like geogrids, geocells and geotextiles due to their multi-functional behaviour has been used in the control of reflection cracking in overlays, as separator- filter – drain at clay sub grades, as reinforcing factor in soft-soils. The current study focuses upon geocell strengthened flexible pavements over soft soils using KENPAVE software. The present study concludes to suggest Geocell strengthened sub-base flexible pavements in which a decrease of the pavement section by approximately 13%.
