The 2019 International Airfield and Highway Pavements Conference was held July 21-24, 2019 at the Holiday Inn Chicago Mart Plaza River North , in Chicago, Illinois, USA. Sponsored by the American Society of Civil Engineers’ (ASCE) Transportation and Development Institute (T&DI), the Conference included a presentation by Jerry Voigt, President and CEO-ACPA onVISION2040 initiative. The presentation provided a long-term view of technology-driven changes anticipated in the next 20 years, as well as projections on how the concrete pavement industry will both adapt to and drive innovation.

Eric Ferrebee, Chairman-ACPA presented on concrete pavement preservation and rehabilitation techniques and also did a poster presentation on PavementDesigner.org—the cement and concrete industries’ pavement thickness design platform. Eric also participated in the highway- and airfield-pavements committee meetings. PavementDesigner.org: https://www.pavementdesigner.org
Two PRE-CONFERENCE WORKSHOPS were held on Sunday, July 21:
1 – Peter Taylor and Gordon Smith, CP Tech Center were among presenters in the Performance Engineered Mixtures (PEM) Workshop
The fundamental shift associated with performance-engineered mixtures is the transfer of risk and control from the highway agency to the contractor. Agencies gave contractors the chance to innovate and meet the performance criteria specified by the agency in the most economical and environmentally sustainable manner. The ultimate vision of the PEM program is for highway agencies to have faster and better-quality assurance tests, optimized mixtures that lead to cost savings, and longer-lasting pavements. Topics for presentation and discussion at the workshop—a cooperative activity of the FHWA and the ACPA—were:
- Performance Engineered Pavements (Asphalt and Concrete), Richard Duval, FHWA
- Performance Engineered Mixtures (PEM) for Concrete, Michael Praul, FHWA
- Concrete PEM Tests, Dr. Peter Taylor, National Concrete Pavement Technology Center
- Concrete PEM Pooled Fund, Cooperative Agreement, and State Implementation, Gordon Smith, National Concrete Pavement Technology Center
- Strengthening Asphalt Quality Assurance, Tim Aschenbrener, FHWA
- Navigating the Performance Test Jungle: Recommendations to Implementing Performance Tests, Dr. David Mensching, FHWA
- MaineDOT Experience with Performance Engineered Mixture Design for Asphalt, Derek Nener-Plante, MaineDOT
2 – Jeffrey Gagnon, Federal Aviation Association (FAA)
Pavement Evaluation Software
Developed and maintained by the FAA (U.S.), a suite of free software tools including the PAVEAIR, BAKFAA, and ProFAA computer programs, provides publicly available tools for pavement evaluation and analysis.
—FAA PAVEAIR 3.2 is a web-based Airport Pavement Management System (APMS) designed to assist organizations in the assessment, management, and maintenance of their airfield pavement networks.
—BAKFAA 2.1.0.1 performs backcalculation of pavement material properties using Heavy Weight Deflectometer/ Falling Weight Deflectometer (HWD/FWD) data.
—ProFAA computes pavement elevation profile roughness indices. This FAA software workshop is intended for engineers practicing airport pavement evaluations.
Participants in the workshop:
- Learned the principles of pavement evaluation using these software programs.
- Participated in hands-on demonstrations of the software.
- Discovered how recent and scheduled improvements will enhance the functionality of each program. Participants brought their own laptops to install the software so they could follow along through the training and pavement evaluation demonstrations.
TDI supports the advancement of integrated transportation and development that is safe, secure, and sustainable.
