Report Cites Superior Features of Concrete Pavements

A recent publication from the Australian Society for Concrete Pavements* says, “concrete pavements surpass asphalt pavements in all aspects.”

“Concrete Pavement Value: Economic, Operational and Community Benefits,” is a two-page “pavement note,” which explains that concrete pavements provide:

  • 25% lower construction costs vs. full-depth asphalt;
  • 50 to 60% lower maintenance costs over a 40-year life span; and
  • 50% fewer road closures and traffic disruptions.

The information was based on a metareview of 15 research reports, technical resources, and statistical information from well-known subject matter experts and technical organizations, including ACPA. Drawing on published resources, the pavement note presents facts clearly and concisely, and with supporting graphics and references.

The document says “(c)oncrete pavements are significantly lower in construction cost, maintenance cost and, consequently, whole of life cost. Additionally, they are smooth, skid resistant, more rapidly constructed, less labour-intensive, less equipment-intensive, more durable, and more
available in-service.” Click here to see the pavement note.

* The Australian Society for Concrete Pavements was founded in October 2007 to facilitate improvements in the design, construction & quality of concrete pavements in Australia through education, information and technology transfer, and research.

ACPA Presents Concrete Pavement Jointing Training

ACPA partnered with the Florida Chapter to present an hour-long training session for Florida DOT officials, engineers, consultants and others with an interest in quality concrete pavement construction.

The webinar focused on concrete pavement jointing, with Eric Ferrebee and Mark Snyder each presenting information to close to 60 professionals.

Eric covered topics such as why we joint concrete pavements, types of joints, joint spacing and aspect ratio, and joint layout for intersections. Mark covered dowel and tie-bar design considerations, construction details and joint construction consideration.

Technical resources and other information, including access to existing recorded webinars were also provided to attendees. This session and the resources offered were provided as a substitute for in-person workshops, which because of COVID-19, were no longer feasible.

At the end of the webinar Eric and Mark offered a Q&A session, which lasted close to 30 minutes. ACPA and the Florida Chapter are tentatively planning in-person training on the topic later this year.

Report Presents Latest AID-PT Program Update

The latest FHWA annual report on the Accelerated Implementation and Deployment of Pavement Technologies (AID-PT) program presents highlights and case history examples of key deliverables.

Hari Kalla, FHWA Associate Adminstrator for Infrastructure, opens the report with comments about the program, including recent focus areas, including pavement design, construction, sustainability, data management, and training

The 47-page report includes specific examples of programs, activities and specific products.  A few of the coverage areas of particular interest to the concrete pavement construction community include concrete pavement preservation, precast concrete pavement  systems, and the agency’s Concrete Clips education & tech transfer video series, which ACPA promotes actively.  The report also includes an update on the Mobile Concrete Technology Center (MCTC) and related accomplishments and activities..

Jerry Voigt provided some comments on behalf of the concrete pavement industry.  ““Profound changes are happening all around us and at an ever-increasing pace! Driving these changes are population increases and shifts, consumer trends, and the increased use of technology in almost every facet of life. These and other factors are transforming the roles of highways and the people responsible for their design, construction, and rehabilitation.”

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 the end of this fiscal year.  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.

FAA & TriServices Discussions Yield Positive Results

A series of meetings last week set a positive tone for developing a collaborative applied research & technology program and for improving airport concrete pavement specifications. 

Representatives of ACPA met with John Dermody, Director of the Office of Airport Safety and Standards; Khalil Kodsi, Airports Division Manager; and Doug Johnson, FAA Headquarters Paving Engineer. Gary Mitchell, ACPA’s Vice President of Airports, says they had a productive discussion about various research topics, as well as how to structure an applied research program that would facilitate agency and industry collaboration.

As ACPA has been reporting, Gary and others representing the concrete pavement industry have fostered an excellent relationship with the agency and have been working closely with officials from  FAA Headquarters and the William J. Hughes Technical Center to discuss both a viable collaboration and specific focal points for applied research that is focused on improving the quality of concrete pavements. As reported in ACPA  TODAY, the 2020 appropriations legislation, signed into law in December, provides funding for R&T similar to what ACPA developed and led to create the Accelerated Implementation and Deployment of Pavement Technologies (AID-PT) program with the FHWA. ACPA worked closely with PCA and NAPA on both programs, and it should be noted that the asphalt pavement industry is also engaged in similar discussions about R&T with FAA officials.

Also last week, there were two meetings with the US military Tri-Services, the first of which involved military officials, ACPA staff, Airfield task force Chairman Martin Holt (Interstate Highway Construction), other contractors, vendors and architectural and engineering (A/E) firms to discuss specifications. The group had a thorough and detailed discussion about the military’s Unified Facilities Guide Specifications, all with the aim of fine tuning and improving the concrete pavement spec.

Later in the week, Gary, Martin Holt and Jerry Voigt, met with the Tri-Services to discuss specifics ways to help improve concrete pavements and concrete pavement construction. “We agreed to enter into a close working relationship,” Gary says, adding that this relationship is focusing on a “better understanding of each other’s perspectives.”

He adds the military has some very exacting standards for quality, and those standards have everything to do with both the overall mission, as well as the type of aircraft taking off and landing on pavements, often in less than ideal conditions. “We understand and appreciate the Department of Defense requirements and why they are so exacting.”

The working relationship is very important and underscores the important point that our goals are the same: to increase the quality of airfield concrete pavements, he says.
