New composite foundation model for portland cement concrete pavement

For a structural analysis in cement concrete pavement,this paper gives a new bi-parameter foundation model with the Transfer Matrix method.A new model, named T model, fits the Winkler model together with axisymmetrical multi-layered half space model,and it has the merit of the two classical models.Finally the results of the new model are compared with the modified K-value method in PCA, FAA, etc.
