Noncontact Nondestructive Determination of Pavement Deflection under Moving Loads
This report presents a procedure for nondestructively evaluating and predicting the deflection response of various flexible pavements to loads imposed by different aircraft. Transfer function theory is used to form the basis of a pavement evaluation and response scheme. Two mobile systems were developed for the measurement of pavement deflections; the Light Emitting Diode (LED) system and the Linear Variable Differential Transformer (LVDT) system. The report concludes that the rapid nondestructive measurement of pavement deflections due to moving prototype loads is feasible and that a total nondestructive evaluation scheme based entirely on the use of prototype loads and measured deflections can be fabricated to evaluate and predict instantaneous response and cumulative effects of loads of various magnitudes and configurations.
