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. This interim report investigates the merits and the feasibility of using FWD and Spectral Analysis of Surface Waves (SASW) in the urban environment where most of the assumptions made in evaluating rural pavements are no longer valid. The report documents the results of NDT tests performed in New York City, Syracuse, and Princeton. The authors propose a process for selecting both network level and project level repair strategies for NYC pavements.
