Workshop: Maintenance of Traffic Successes, Challenges and Misperceptions
The American Concrete Pavement Association (ACPA) Mid-Year Meeting, held June 23-25, 2015, kicked off with a Workshop titled “Maintenance of Traffic” (MOT) aimed at showcasing successes, addressing misperceptions, and capturing MOT best practices with various types of facilities and paving strategies (construction, rehab, overlays, etc.).
The workshop included presentations by engineers from the Federal Highway Administration (FHWA), the Illinois Toll Highway Authority, and several construction and engineer firms. The presentations and the open discussions provided both a clear direction and a sense that there are many positive examples of how ACPA members are meeting the demand of paving under traffic … and doing so successfully.
Immediately following the workshop, there was a meeting of the new ACPA MOT Task Force to developed a clear course of action to capitalize on strengths and address challenges. The MOT task force is led by ISCP Members, Randy Riley, ACPA-Illinois Chapter, and Jim Mack, Director, Market Development-Cemex. The MOT task force staff contacts are ISCP Members Leif Wathne, Executive Vice President–ACPA and Eric Ferrebee, Technical Services Engineer-ACPA.

Three Concrete Paving Task Force Meetings:
1. Pavement Design Task Force Discusses Resource Needs … The task force discussions included:
- One of the key issues discussed during the Pavement Design Task Force meeting was the proposal to develop a unified pavement design software that could be used for all types of concrete pavement facilities and types of paving—the visuals, functionality, ease of use, and other matters. A flow chart developed by Eric Ferrebee was a useful tool for the discussion, and helped capture task force members’ suggestions and specific topics that needed further exploration.
- ACPA’s continuing efforts to develop technical and promotional information on common design issues, as well as training for Chapter/States and pavement designers. The group is exploring whitepapers to explore pavement design issues.
- Two online design programs: IPAVE and PaveXpress—which ACPA has evaluated and developed a “Perspectives Document” to identify shortcomings.
The pavement design task force is led by ISCP Members Randy Riley, ACPA-Illinois Chapter, and Jim Mack, Director, Market Development-Cemex; with Eric Ferrebee serving as the staff liaison. For the full Pavement Design Task Force article and more information on the ACPA website, please click here.
2. Jointing Task Force Reviewed Technical Topics, Tech Transfer … The Jointing Task Force discussed a number of current topics:
- The NC2 High Performance Dowel Committee Report—an online training course opportunity
- A number of recently completed deliverables—including the organization of jointing materials on ACPA’s Wikipave™ online resource
- A presentation on a “Joint Reservoir Video System” covered a device and a method for video recording joints and joint sealants in place.
- Suggestions for refining ACPA’s dowel alignment specification—including guidance on diverging diamond (or double crossover diamond) interchanges
The jointing task force received staff support from ISCP Past President Mark Snyder, ACPA Consultant. For the Jointing Task Force Update full article on the ACPA website, please click here.
3. Airport Task Force Focuses on Training … ACPA’s Airport Task Force meeting included discussions:
- The Second pilot program of the U.S. Army Corps of Engineers (USACE) accredited training program—which ACPA will be delivering in the fall of 2015.
- ACPA will develop a web-based training on “Best Practices of Airfield Paving” with the Federal Aviation Administration (FAA).
- ACPA will continue to work with contractors and owners’ representatives on technical issues—in particular, helping to create a better understanding of the FAA P-501 specification and Unified Facilities Criteria (UFC) 32 13 11 specification.
- ACPA will continue to work on the USACE Central Mix Plant Certification program, Airfield Smoothness Specification, and a number of direct support issues.
