A significant number of the pavement structures fail a long time before their design life due to the poor quality of construction materials, inadequate compaction, inadequate preparation of the subgrade, overloading, etc. There are two methods to overcome this issue. The primary choice is by increasing the thickness of various layers and the other alternative is by increasing the strength and rigidity of the pavement layers which lowers stresses on the pavement layers. Rutting is a common feature observed in flexible pavements supported on weak subgrades. Reinforcing the weak subgrades is one of the promising alternatives to alleviate the pavement surface rutting. Geocell reinforcement, a three-dimensional confinement increases the load-carrying capacity of the soil. In the present study, the improvement in the strength and stiffness of flexible pavement systems using geocell confinement is investigated by placing geocell in the subgrade soil. The finite element analysis of the model will be done by using the ANSYS tool and analytical results such as Strains generated in each layer and propagation of stresses are studied.
