Paragraph one

As the latest of three multi-year street, asset and pavement management assignments for the agency, WSP USA reviewed and recommended improvements to NYCDOT’s initial pavement deterioration model to be used in forecasting the condition of -- and support the determination of treatments for -- the city’s street network.

WSP also analyzed the pavement condition data being gathered by NYCDOT pursuant to our 2015 recommendations to enhance the agency’s pavement management analysis capabilities.

Among those recommendations was that the agency adopt a Pavement Condition Index (PCI)-based method for collecting condition data. For the latest assignment, we compared the new condition ratings under NYCDOT’s modified PCI-based method with those determined for the same street segments using the agency’s previous condition assessment method.

We also reviewed the process followed by the street assessment inspectors relative to our 2015 recommendations and the Asphalt-Surfaced Pavement Distress Identification Manual we had designed for NYCDOT.

NYCDOT was provided with a set of recommendations to improve pavement deterioration modeling, as well as a more reliable base model for its use grounded in the engineering principles underlying pavement deterioration. We then continued to work with NYCDOT toward acquiring model-useful data sets regarding pavement structure and heavy vehicle traffic levels to improve the base model.

Recommendations to improve the condition data gathering and rating process will help NYCDOT to improve its pavement maintenance and rehabilitation decision-making.
