• Abstract:
  The objective of this exploratory and high-risk study is to investigate how the gradually varied elastic moduli affect the load response of the flexible pavement. Instead of using the average moduli, the elastic moduli of each layer in a pavement structure are modeled to be gradually varied within the layer. To consider the elastic moduli gradients, the layer is subdivided into many sublayers with every sublayer having a constant modulus. Therefore the conventional 2-3 layers pavement is modeled by a multi-layered structure, with up to 100 sublayers. For such multilayered pavement, a unique, fast and innovative program, named MultiSmart3D, was developed.
