摘要：	Since 2000, Massachusetts has been involved with numerous field trials of experimental hot mix asphalt mixtures. These experimental mixtures included several pilot projects using the Superpave mixture design methodology, utilization of warm mix asphalt technologies, asphalt rubber mixtures, latex or polymer modified asphalt mixtures, and reflective crack relief layer mixtures. All these types of mixtures are placed to achieve a longer service life and specific outcomes in terms of performance of the pavement. The research team solicited input from MassDOT to identify projects that were of interest for monitoring. Twelve projects were identified for inclusion in the study. For each project, a plan was developed to monitor the experimental mixture performance. Ultimately, it was decided that condition data (distresses, rutting, cracking, roughness, etc.) would be measured periodically during the duration of this project to monitor project performance. Generally, based on the monitoring plan and associated thresholds for condition indices, the experimental mixtures placed at the selected projects have provided acceptable performance in terms of cracking, rutting, and ride quality. Furthermore, it is suggested that a final specification be developed for mixtures exhibiting acceptable performance.
