Evaluation of Long-Term Pavement Performance and Noise Characteristics of the Next Generation Concrete Surface

摘要

This report documents the construction of the first Next Generation Concrete Surface (NGCS) by the Washington State Department of Transportation (WSDOT). A 1,500 foot test section was installed on the eastbound lanes of I-82 near Sunnyside, WA in October of 2010. Baseline measurements of noise, friction, wear and smoothness are reported. The sound intensity levels of 101.6 and 99.6 for the outside and inside lanes, respectively, are within the range reported for other NGCS projects. A literature review is provided that documents the development of the NGCS process as well as descriptions and results from the initial field trials in the U.S.
