Nondestructive deflection testing and backcalculations for pavements : proceedings of the symposium 'Capabilities and limitations of nondestructive deflection testing (NDT) and backcalculation for estimating stiffness of paving materials', August 19-21, 1991, Nashville, Tennessee. As part of that symposium, a workshop was held to reach consensus on current capabilities and limitations, and directions to pursue for improvements. This Record contains 13 technical papers and 7 other papers related to the theme of the symposium. In addition, the Record contains reports prepared by Irwin, Thompson, and Smith, who led the discussion groups on practical limitations and what can be done to overcome them, backcalculation limitations and future improvement, and current and future applications of nondestructive deflection measurements, respectively.
