ONTWIKKELING VAN EEN DRIE-DIMENSIONAAL EINDIGE ELEMENTEN MODEL VOOR ELEMENTENVERHARDINGEN

This paper describes the development of a three-dimensional finite element program for concrete block pavements, which consists of two submodels. In the first (for the total concrete block pavement structure) the rectangular concrete paving blocks, in herringbone bond, are modeled by "rigid bodies" that are interconnected by springs in x, y and z directions. Four layers of elastic elements represent sublayers of the bedding layer, the base (if any) and the sand subbase. The subgrade is represented by vertical springs. The model is subjected to traffic loads. Determination of the stresses within the concrete paving blocks requires a second submodel of a single, elastic concrete block which is loaded by forces obtained from the first submodel. The first calculation results show among others that the properties of the concrete block layers have a small effect on the behaviour of the total concrete block pavement structure. Furthermore they indicate that concrete blocks with a thickness of less than 80 mm could be resistant to traffic loads, but in practice this is not always the case.
