Comparative Evaluation of Deflection and Wave Propagation Nondestructive Testing Methods for Pavements: Implications for Implementation at State and Local Levels (Excerpts)
<p>In New York City, as in other highly urbanized areas, several factors make it too difficult to apply pavement management systems methodology in the traditional way. Two of those factors are: underground utilities and utility cuts; together, they are the two most significant life-limiting factors for NYC pavements. Non-Destructive testing (NDT) techniques such as the Falling Weight Deflectometer (FWD) have been successfully used to evaluate the conditions of rural pavements.
