Need for better road transportation facility is increasing day-by-day and in order to fulfill the need researches are carried out from a long period. Construction of a road becomes simple only after the design of a pavement is complete, today engineers are facing challenges in designing pavements that can serve a long duration without premature failures. Pavement design is one of the most important aspects of any transportation project. Poor and inadequate design may result to reduce the life of flexible pavement and increase the annual maintenance cost. It becomes the prime importance to design a durable and economic pavement structure. A durable structure can be designed only after proper analysis. Multilayered analysis is widely used but it assumes the pavement material to behave linearly which in practice is not true hence analysis of materials with nonlinear behavior is required. To obtain accurate response it is essential to analyse the pavement structure considering responses from each and every particle which is a tedious process with multilayered program, to make obtain accurate responses a powerful method like finite element method is used. In the present work an attempt has been made to study and analyse a pavement structure using a finite element based software tool and compare the results with that of a multilayer based program. Overall response helps in identifying the pavement parameters which has major impact on the performance of the pavement structure, by this it will be possible to design a pavement with long durability and high performance.
