Continuing Long-Term Evaluation of Open Grade Asphalt for the Reduction of Traffic Noise

This paper describes how the California Department of Transportation (Caltrans) is evaluating the effect of highway pavement types on traffic noise. Pavement overlays were applied to a 9-kilometer stretch of I-80 (just east of Davis, California) in June and July of 1998. This provided an opportunity to carefully collect noise data that is associated with a new overlay of open-graded asphalt concrete (OGAC) and to evaluate noise levels as the pavement overlay ages. This paper presents a summary of noise and traffic data collected at various times over the period from June 1998 through June 2003, including baseline data that represents noise conditions associated with the old pavement prior to the overlay. The study is continuing into its 6th year.
