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
