Stone Matrix Asphalt -- SR 524, 64th Avenue West to I-5

This report documents the first stone matrix asphalt (SMA) pavement constructed on the Washington State highway system. This documentation includes a brief summary of the required design, production and construction practices, a brief description of the existing pavement, results of a pre-contract meeting, difficulties encountered during the construction project, and lessons learned. It was anticipated that a number of difficulties would occur on this first SMA pavement project; however, the experience obtained on this project will enhance the construction of future SMA projects.
