The meeting agenda included welcoming attendees and approving prior minutes, general communications, updates on recent outreach and communication efforts, and progress reports on work in progress. Key discussion points involved administrative clarification of applicable projects for analysis, refinements to the impact assessment and offset plan procedure, and review of a companion worksheet. The committee planned to review test cases and conduct an emissions impact scenario analysis, followed by a public comment period and a review of meeting actions.

Minnesota Department of Transportation Workplan 2025-2029
This workplan outlines Phase II of the Continuous Asphalt Mixture Compaction Assessment Using Density Profiling System (DPS) project, led by the Minnesota Department of Transportation. Its primary aim is to enhance asphalt pavement compaction assessment using non-destructive DPS technology to improve pavement quality, reduce destructive testing, enhance safety, and extend pavement longevity. The plan addresses key priorities including data analysis and ghost implementation support, personnel training, benefit-cost analysis, and regional data support through tasks such as universal analysis software development, supporting ghost implementations, foundational research, personnel training and materials development, economic evaluations, and communication and stakeholder engagement.

TPF-5 (443) Density Profiling System Technical Working Group Meeting Summary Report
The meeting included discussions on the next phase of the DPS pooled fund, potential DPS demonstrations at the NRRA workshop, and a possible TWG meeting at the ISIC conference. GSSI presented their research and development, highlighting the benefits, considerations, and limitations of DPS under a roller, including the need for calibration and adjustments for surface texture and temperature. UNH presented an experimental plan for data correlation analysis between laboratory and field dielectric measurements, focusing on mixture properties, dielectric and density measurements, and surface texture. The North Dakota Technology Test Project was reviewed, which involves paving with semi-autonomous equipment and testing DPS along with other technologies. The development of a Mix Calibration Repository on the FHWA CHARISMA platform was discussed, and an overview of the AASHTO Sample Dielectric was provided.
