Quieter Pavements Survey

This study looked at the performance of quieter pavements in use in the United States of America and Europe with specific emphasis on those states that are using open-graded mixes for both friction or porous courses on an ongoing basis. All States were contacted and 34 states responded with information on their use of open-graded mixes and stone matrix asphalt (SMA) mixes. Eleven states were able to provide an estimate of the range and average service life of their open-graded mixes and three states provided information on the service life of their SMA mixes. Specifications for open-graded mixes and SMA mixes were compiled from 20 states and compared to Washington State’s open-graded friction course mix and the open-graded mix used on recent test sections built by the Washington State Department of Transportation.
