The FHWA Intelligent Compaction National Workshops were the continuing effort to fulfill the IC Road Map developed under the TPF IC project in order to provide three (3) regional training workshops to States and industry around the country. The first workshop was conducted on December 13, 2011 in Atlanta, Georgia. The second workshop was conducted on February 28, 2012 in Salt Lake City, Utah. The third workshop was conducted on May 3, 2012 in Bloomington, Minnesota. Reports were produced for each workshop. This document is the report summarizing all three workshops and recommendations for future action.
This document summarizes the discussion and findings of the 4th workshop held on October 27–28, 2015 in Frankfort, Kentucky as part of the Technology Transfer Intelligent Compaction Consortium (TTICC) Transportation Pooled Fund (TPF-5(233)) study. The TTICC project is led by the Iowa Department of Transportation (DOT) and partnered by the following state DOTs: California, Georgia, Iowa, Kentucky, Missouri, Ohio, Pennsylvania, Virginia, and Wisconsin. The workshop was hosted by the Kentucky Transportation Cabinet and was organized by the Center for Earthworks Engineering Research (CEER) at Iowa State University of Science and Technology. The objective of the workshop was to generate a focused discussion to identify the research, education, and implementation goals necessary for advancing intelligent compaction for earthworks and asphalt. The workshop consisted of a review of the TTICC goals, state DOT briefings on intelligent compaction implementation activities in their state, voting and brainstorming sessions on intelligent compaction road map research and implementation needs, and identification of action items for TTICC, industry, and Federal Highway Administration (FHWA) on each of the road map elements to help accelerate implementation of the technology. Twenty-three attendees representing the state DOTs participating in this pooled fund study, the FHWA, Iowa State University, University of Kentucky, and industry participated in this workshop.
This document summarizes the discussion and findings of a workshop on intelligent compaction for soils and hot-mix asphalt held in West Des Moines, Iowa, on April 2-4, 2008. The objective of the meeting was to provide a collaborative exchange of ideas for developing research initiatives that accelerate implementation of intelligent compaction (IC) technologies for soil, aggregates, and hot mix asphalt. Technical presentations, working breakout sessions, a panel discussion, and a group implementation strategy session comprised the workshop activities. About 100 attendees representing state departments of transportation, Federal Highway Administration, contractors, equipment manufacturers, and researchers participated in the workshop.
TRB's National Cooperative Highway Research Program (NCHRP) Report 676: Intelligent Soil Compaction Systems explores intelligent compaction, a new method of achieving and documenting compaction requirements. Intelligent compaction uses continuous compaction-roller vibration monitoring to assess mechanistic soil properties, continuous modification/adaptation of roller vibration amplitude and frequency to ensure optimum compaction, and full-time monitoring by an integrated global positioning system to provide a complete GPS-based record of the compacted area--
Intelligent compaction (IC) technology integrated with global positioning system (GPS) provides 100 percent coverage for compacted earth materials and hot mix asphalt (HMA) conditions. Using IC shows significant potential for enhancing the abilities of governmental agencies and contractors to construct better, safer, and less expensive transportation infrastructure projects. The Iowa Department of Transportation (DOT) and the Earthworks Engineering Research Center (EERC) at Iowa State University have organized three national level annual workshops (2008-2010) to provide a collaborative exchange of ideas and experiences, share research results, and develop research, education, and implementation initiatives for IC.
