NUMERICAL CALCULATION FOR EQUIVALENT SINGLE WHEEL LOAD (ESWL)

Abstract

The flexible pavement layers attach at every hours during the day to hundred thousand from several traffic loading according to number of axles, number of wheel for each axles (Dual and Triple …,etc) and tire pressure. These different types of above variable generate stresses, strains and defilations in the pavement layers (with overlap stresses and deflection) caused to fatigue of pavement to reduced pavement life. In order to design exchange these loads to Equivalent Single Wheel Load (ESWL). Little programs are available to solve this problem as an exact solution. In this work using 3D finite element model make by SAP 2000 program based on the equal maximum vertical interface deflection for equal contact area concept. The results are compared with the analytical solution obtained from Kenlayer Computer program.
