DEVELOPMENT OF A FINITE ELEMENT PROGRAM FOR CALCULATING ON CONCRETE BLOCK PAVEMENTS

ONTWIKKELING VAN EEN EINDIGE ELEMENTEN PROGRAMMA VOOR HET REKENEN AAN BETONSTEENVERHARDINGEN

This paper introduces a finite element based model for concrete block pavements, which uses modified axial symmetric elements that do not develop tangential stresses. Using such elements the disadvantages of an axial symmetric representation of a concrete block layer are overcome to a large extent. Modelled blocks can now rotate and translate freely, as in reality. As a result the model no longer comes to tensile stresses in the bedding layer. Since the modelled block layer no longer has a self confining property, the need for an adequate edge restraint is now shown by the model. The model is described and the results of linear elastic and non-linear elastic calculations are presented. In these calculations the model was loaded each time by a 50 kN load. The results show that the model provides insight into the stresses occurring in the bedding layer of the concrete block pavement. It does this by modelling the behaviour of the block layer similar to the behaviour of such a layer in reality. The model is considered to be a good alternative for a three-dimensional model.
