Federal Highway AdministrationUS Transportation CollectionOn October 27\u201328, 2015, the Kentucky Transportation Cabinet (KYTC) hosted the 4th workshop forthe Technology Transfer for Intelligent Compaction Consortium (TTICC), a Transportation Pooled Fund(TPF\u20135(233)) initiative designed to identify, support, facilitate, and fund intelligent compaction (IC)research and technology transfer initiatives. The following were the key objectives of the workshop:\u2022 Review and exchange experiences of state DOTs in implementing IC for earthwork and Hot MixAsphalt (HMA)\u2022 Review the existing IC specifications\u2022 Facilitate a collaborative exchange of information between state DOTs, the Federal HighwayAdministration (FHWA), and industry to accelerate effective implementation of IC technologies\u2022 Update the IC roadmap for identifying key research/implementation/education needs, and actionitems for the TTICC group, the FHWA, and industryThe workshop\u2019s attendees\u2014representing seven state DOTs, the FHWA, Plantmix Asphalt Industry ofKentucky, and Iowa State University\u2014reviewed the current IC specifications, discussed recent IC pilotspecifications implemented by state DOTs or demonstration projects conducted by state DOTs, discussedthe challenges being experienced by the DOT personnel during implementation and potential solutions,and voted and brainstormed IC research, implementation, and educational needs.A key outcome of the workshop was the evaluation and update of the IC Road Map, a prioritized listof IC technology research/implementation needs initially created in a 2008 IC workshop meeting andupdated in the previous workshops. The top three IC research/implementation needs are now (1) datamanagement and analysis, (2) sustainability and return of investmen, and (3) correlations between ICand in situ test measurements. The revised IC road map is presented in Table 1. After updating the ICroadmap, the group identified action items for the TTICC group, the FHWA, and industry for advancingthe top three road map elements.This forum served to facilitate information exchange and collaboration and developing a list of actionitems to advance and accelerate implementation of IC technology into earthwork and asphalt constructionpractice and developing a short list of items that the TTICC team can use to help advance the ICroad map research/implementation priorities. An IC workflow process has been developed as part of thiseffort linking the design, construction, and testing phases of a project
