Composite Computational Model for Portland Cement Concrete Pavement

It is well known that there are two models in pavement calculation, one is the Winkler model and the other is a multi-layered elastic model. In this paper, a new bi-parameter computational model is presented for analyzing layered base and subgrade in Portland cement concrete pavement. In the new model the subgrade is represented by a group of springs with k-value, and the subbase/base are modeled by elastic multi-layer. However, the Winkler model and the Boussinesq and Burmister models only use one material parameter, the modulus of reaction k or elastic modulus E. So the new model has the merit of the two classical models. Finally, the new model is compared with the enhanced k-value method in Portland Cement Association (PCA), Federal Aviation Administration (FAA), etc. methods.
