TPF Intelligent Compaction Project

This study (from 2008 to 2010) was initiated under Transportation Pooled Fund (TPF) Solicitation No. 954, which includes 12 participating State department of transportation (DOTs): Georgia, Indiana, Kansas, Maryland, Minnesota, Mississippi, North Dakota, New York, Pennsylvania, Texas, Virginia, and Wisconsin.

The purposes of this project are to:

• Accelerate the development of IC QC/QA specifications for subgrade soils, aggregate base, and HMA pavement materials. The focus of the technology will be to provide a reliable method to capture the maximum potential value added from current IC technology and currently used/available QC/QA field-testing equipment (dynamic cone, FWD, Plate Load Tests, Nuclear Density, Moisture, temperature, cores, etc.).
• Develop an experienced and knowledgeable IC expertise base within the participating State DOTs.
• Identify and prioritize needed improvements to, and research for, IC equipment and QC/QA field-testing equipment. Prioritization will be based on the potential for: simplifying IC usage, achieving greater IC value (cost benefit), and improved accuracy.

Task Working Group (TWG)

To facilitate the implementation of this project, we formed a virtual team or Task Working Group (TWG) from the FHWA, IC project team, IC facilitator, TPF pooled fund States, and IC roller vendors.

Here is our TWG team structure and a recent photo with the majority of the team members.
