Modeling Flexible Pavement Response to Truck Loads using Finite Element Simulations

This paper introduces an analytical approach to determine pavement responses for different axle loadings and truck configurations. A 3-D finite element program is used to model the pavement and analyze total permanent deformation (TPD) response for 2 State highway classes. Various steering, single, tandem, and tridem axle loadings are modeled. The main aim of the study is to realize that the TPD responses of truck loads can be attained and compared as relative damage for different axle types, axle loads, and truck loading scenarios including the whole truck model. The study finds that relative damage decreases with the increase of the number of axles in an group and when loaded trucks comply with the Federal Highway Administration gross vehicle weight limits.
