dc.description.abstract A methodology for evaluating the condition of jointed portland cement concrete pavements (JCP) by non-destructive deflection testing was recently applied on the National Route 4 (N4) between Middelburg and Witbank. A set of two calibrated Multidepth Deflectometers (MDD) measured traffic-associated vertical absolute deflections at both sides of a transverse joint. A piezo-electric film trip triggered the data accumulation process. Joint efficiencies were then calculated from absolute deflections measured by both MDDs. Joint efficiency is one of the inputs of theoretical-mechanistic models for the calculation of stresses and deflections in the pavement structure. In this paper, charts developed from the ILLI-SLAB progam code illustrate how stresses in concrete pavements vary for different joint efficiencies and moduli of subgrade reaction. en_US
