Materials Properties and Optimum Geometries for the Design of Noise Walls

Highways built by the Arizona Department of Transportation (ADOT) using Federal Highway Administration (FHWA) funding must comply with FHWA noise abatement standards. Constructing noise walls parallel to a roadway is one traditional strategy used to reduce roadside noise. Most noise walls are currently designed to reflect sound. However, new materials and designs are emerging that may provide more effective control of roadway noise. This project will identify materials and designs that may have advantages over traditional, reflective noise walls, summarize available information regarding the effectiveness of these materials and designs in reducing roadway noise, and recommend a field test to evaluate the most promising materials and designs in improving roadway noise reduction. Materials would be evaluated based upon constructability and life cycle costs/maintenance.
