  • Abstract:
    On October 27–28, 2015, the Kentucky Transportation Cabinet (KYTC) hosted the 4th workshop for

    the Technology Transfer for Intelligent Compaction Consortium (TTICC), a Transportation Pooled Fund

    (TPF–5(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:

    • Review and exchange experiences of state DOTs in implementing IC for earthwork and Hot Mix

    Asphalt (HMA)

    • Review the existing IC specifications

    • Facilitate a collaborative exchange of information between state DOTs, the Federal Highway

    Administration (FHWA), and industry to accelerate effective implementation of IC technologies

    • Update the IC roadmap for identifying key research/implementation/education needs, and action

    items for the TTICC group, the FHWA, and industry

    The workshop’s attendees—representing seven state DOTs, the FHWA, Plantmix Asphalt Industry of

    Kentucky, and Iowa State University—reviewed the current IC specifications, discussed recent IC pilot

    specifications implemented by state DOTs or demonstration projects conducted by state DOTs, discussed

    the 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 list

    of IC technology research/implementation needs initially created in a 2008 IC workshop meeting and

    updated in the previous workshops. The top three IC research/implementation needs are now (1) data

    management and analysis, (2) sustainability and return of investmen, and (3) correlations between IC

    and in situ test measurements. The revised IC road map is presented in Table 1. After updating the IC

    roadmap, the group identified action items for the TTICC group, the FHWA, and industry for advancing

    the top three road map elements.

    This forum served to facilitate information exchange and collaboration and developing a list of action

    items to advance and accelerate implementation of IC technology into earthwork and asphalt construction

    practice and developing a short list of items that the TTICC team can use to help advance the IC

    road map research/implementation priorities. An IC workflow process has been developed as part of this

    effort linking the design, construction, and testing phases of a project.
