A study on behavior of block pavement using 3D finite element method



Three dimensioned finite element analysis were conducted on concrete block paving. In order to verify the calculated results, an experimental case study was analyzed. Good agreement was observed between the measured and the calculated results. Based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement which can take into account; the sub grade and pavement layers properties as well as the tire pressure and the number of repetitive loads. In addition by using 3D finite element model mechanism of interlocking between pavers was discussed. Parametric study were conducted on 3D models and it was found that jointing width, shape, size and thickness of blocks have a significant influence on the behavior of block pavement.
