Field evaluation and computer simulation of undoweled transverse joints in rigid pavements. 12th Annual Transportation Convention, 1992, University of Pretoria, Pretoriahttp://hdl.handle.net/10204/10705Paper delivered during the 12th Annual Transportation Convention, 1992, University of Pretoria, PretoriaA 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.enJointed portland cement concrete pavementsJCPMultidepth DeflectometersMDDJoint efficiencyField evaluation and computer simulation of undoweled transverse joints in rigid pavementsConference PresentationBalmaceda, P., & De Beer, M.
