Concrete Pavements Prominent at SWIFT Conference

ACPA was among several concrete pavement industry organizations participating in the 2017 Summer Winter Integrated Field Technologies (SWIFT) conference and trade show, held recently in Halifax, Nova Scotia.

Prior to the formal meeting of the Canadian Airfield Pavement Technical Group (CAPTG), a special workshop was held to address, “How to Design Sustainability Into Airfield Pavements.”

Workshop speakers included Gary Mitchell, P.E., ACPA’s Vice President of Airports and Pavement Technology, and Peter Taylor, Ph.D., P.E., Director of the National Concrete Pavement Technology Center, an ACPA technology partner.  Mitchell presented on concrete pavement recycling practices and technologies. Taylor presented on the importance of the life-cycle perspective and performance-engineered mixtures.

The formal SWIFT meeting followed the workshop and included moderated discussions and presentations.  Industry officials presented on several topics during Tuesday and Wednesday sessions.  These included: 

  • Stringless paving by ACPA’s Mitchell, as well as several ACPA members and technology partners.
  • Runway grooving for improved braking performance and directional control by John Roberts, Executive Director of the IGGA/ACPA Concrete Pavement Preservation Partnership and John Depman, P.E., Senior Estimator, Penhall Company. 
  • Rapid airfield repair using precast by Chris Olidis, P.E., Principal Engineer, Applied Research Associates, an ACPA member.
  • Optimized concrete pavement design by Robert Rodden, P.E., Lead Engineer, PNA Construction Technologies, an ACPA member. 

Also, moderating the Wednesday technology track was Guillaume Lemieux, Director, Markets and Technical Affairs, Cement Association of Canada, an ACPA affiliate.

SWIFT offers the airport community the opportunity to gather and learn about new pavement design, construction, evaluation and maintenance techniques; materials; chemicals; systems; and equipment available to keep airports safe and operational while addressing any challenges, at minimal cost, during all seasons.

Open House to Showcase Next Generation Concrete Surface

In the early part of the 2000’s, the concrete pavement industry was challenged to address the issue of noisy pavements.   With a significant investment by ACPA, The International Grooving & Grinding Association (IGGA), and the Portland Cement Association, an extensive research and testing program was undertaken to develop a quiet, safe and durable concrete surface texture. 

The outcome of this effort was the developments of the Next Generation Concrete Surface (NGCS).  NGCS was developed under the auspices of ACPA, and with research and testing by the IGGA/ACPA Concrete Pavement Preservation Partnership (CP3), Purdue University, and the Minnesota DOT’s MnRoad facility, along with testing and implementation support from industry, agencies/owners, Chapter/States, and others interested parties.

Ten years after the technology was first developed, the city of Houston, with approximately 3M SY of this quiet pavement surface, holds the distinction of being the largest single user of NGCS technology in the world. 

On November 15, transportation agency officials, industry officials, members of academia, and other interested parties are cordially invited to participate in the “I-10 NGCS Ride Experience Open House,” in Houston.  

The special event will be held from 10 a.m. to 12:30 (CST) at the Texas DOT’s Houston Headquarters, located at 7600 Washington Ave. 

The day begins with presentations in the District’s conference room, after which, participants will have an opportunity to experience the NGCS surface on a chauffeured drive along a section of I-10.  A luncheon also will be served.  Also, an equipment demonstration will allow participants to view commercial diamond-grinding equipment, along with samples of various types of diamond-ground pavement textures.

The event is jointly sponsored by the IGGA/ACPA CP3, Cement Council of Texas, Texas Concrete Pavement Association, American Concrete Pavement Association, CEMEX, Penhall Company, and the Texas DOT. 

Attendance is free of charge, but advance registration is required.   To register, please contact Larry Scofield at lscofield@pavement.com.

More About NGCS
Since its inception, NGCS has gained wide-spread acceptance across the United States and other countries.  Research reports, a report on the development and implementation of the technology, and other technical information may be downloaded online from the websites of ACPA and the CP3.

FHWA Issues AID-PT Annual Report

FHWA publishes an annual report of AID-PT results and benefits.

The Federal Highway Administration has released its 2017 Accelerated Implementation and Deployment of Pavement Technologies (AID-PT) program annual report.   The 28-page report includes case histories and other summary benefits of the program.

The AID-PT program was the result of a legislative provision that was championed by ACPA and first included in the Moving Ahead for Progress in the 21st Century Act (MAP 21).  This ACPA-led initiative created both a mechanism and funding for the delivery of pavement technology for both the concrete- and asphalt-pavement industries.  

Since 2012, the Federal Highway Administration has administered AID-PT with direct input from industry, including ACPA, which remains actively involved in assisting FHWA with support for the program, including continuing to advocate for renewal of the program in highway reauthorization efforts, as well as communicating program results and benefits to the concrete pavement industry. In 2015,  again with strong support by ACPA and other stakeholder groups, Congress included the program in the Fixing America’s Surface Transportation (FAST) Act, which provides funding through 2020.

Since its inception, the program has resulted in benefits to the concrete pavement community, including contracts and cooperative agreements with the National Concrete Pavement Technology Center (CP Tech Center), an ACPA Technology Partner.  AID-PT has had direct and tangible benefits for highway agencies, contractors, consultants, and academia.  Concrete overlays and performance-engineered concrete mixtures (including the use of recycled concrete aggregates) are two technology initiatives that have received support in the form of outreach, education & training, and technology transfer.

ACPA to Lead Visioning Session for Concrete Pavements

The American Concrete Pavement Association is gathering a group of members and specifiers to envision the future of concrete pavements in the year 2040.  The visioning session, called Vision 2040, will take place after the fall meeting of National Concrete Consortium meeting, on September 21 in Minneapolis.  

Vision 2040 is being modeled after a similar visioning session  that took place 20 years ago. 

The previous initiative was called, “Creating a New Generation of Pavements,” and was initiated by ACPA in 1997.   The result was five goals and a series of prioritized research and development, technology transfer, and technology implementation needs intended to help the industry reach those goals.  The statements were referred to as a “blueprint,” and became the basis for the “Concrete Pavement Road Map” published in 2005.  ACPA estimates about 80% of the blueprint has come to fruition and been completed over the last 20 years.  

Vision 2040 will provide key stakeholders with the opportunity to look forward and revisit needs, discuss aspirations and set priorities for concrete paving.  For more information about Vision 2040, contact Leif Wathne at 202.638.2272 or lwathne@acpa.org.

Pavement Design Web Solution Moves Forward

As reported at the ACPA Mid-Year meeting, the co-branded, web-based pavement design application being developed by ACPA, the NRMCA Research Foundation, and PCA, has taken some decisive steps forward.  

Development efforts led by ACPA’s Andy Gieraltowski and Eric Ferrebee have advanced to the point where many design modules are now ready for beta testing.  ACPA announced the software is also on track for availability in the fall of 2017.

ACPA promoters and project partners selected the name PavementDesigner.org for the new website.  When it goes live, pavement engineers, technical personnel, professors, and students will have a one-stop site to design cement-based pavement solutions.  Previously, the associations sold separate windows-based design applications. 

The new website will be free to use and not require software to be installed or updated.
