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.
