Highway and pavement design plays an important role in the DPR projects. The satisfactory performance of the pavement will result in higher savings in terms of vehicle operating costs and travel time, which has a bearing on the overall economic feasibility of the project. A thorough analysis of the existing pavement is greatly required at this point of time, as an excessive amount of vehicle loads is passing through the project site and it is unknown whether or not the road pavement might sustain its structural integrity. The critical line of equal costs on the plane of CBR versus msa is also identified. This is a swing line which delineates the economic feasibility of two types of pavements. It has been found that the pressure vs settlement curve; pressure vs nodal stress curve ; pressure vs element stress curve are linear for small pressure range and then it become nonlinear. More nonlinearity is seen at higher pressure. Hence material nonlinearity must be considered while analysing and designing flexible pavements. This total work includes collection of data analysis various flexible and rigid pavement designs and their estimation procedure are very much useful to engineer who deals with highways.
