How is reliability considered?
• The stress and strength internally computed by the HIPERPAV system are mean values. Based on these mean values HIPERPAV uses a probabilistic approach to calculate a critical stress and critical strength as a function of the variability associated with the materials and construction procedures for a typical concrete placement as well as the reliability or level of risk selected. As the selected reliability level increases, the critical stresses will be higher and the critical strength will be lower.
