CP Tech Center Announces Overlay Performance Report

The CP Tech Center announced a new study on pavement overlay performance. “Automated Plate Load Testing on Concrete Pavement Overlays with Geotextile and Asphalt Interlayers: Poweshiek County Road V-18,” offers an assessment of the performance of unbonded concrete overlay sections applied in 2008–2009.

The  authors (David White and Peter Taylor) compare overlays constructed in 2008 to 2009 using an asphalt interlayer or a non-woven geotextile fabric interlayer. 

One of the findings was the concrete overlays placed over the geotextile exhibited lower permanent deformation than those placed over asphalt interlayer.

Video Honors Gordon Smith

In case you missed it, we thought you might like to see this very well produced video, which honors Gordon Smith, formerly of the ICPA, and currently with the CP Tech Center.   The video was unveiled at he ICPA’s 54th Annual Workshop last month, but we think it’s worth a look (or a second look).   Click here to see the video, which can also be found on ACPA’s YouTube video channel.

Calling All Contractors: Please Respond to RCA Survey

ACPA is urging contractor members to respond to the Annual Recycled Concrete Aggregate (RCA) Survey for 2017 projects.  ACPA sent the survey early Monday morning, and is requesting responses by Friday, April 13.  

The FHWA has identified concrete pavement recycling as an important area of interest, and has urged industry to gather strategic information. Currently, there is no known source of information that accurately captures the degree with which concrete pavements are recycled or re-used, nor do we know for certain what barriers exist that may hamper the degree of concrete pavement recycling or RCA usage.  This survey, now conducted annually by the American Concrete Pavement Association (ACPA) in partnership with FHWA and National Concrete Pavement Technology Center (CPTech Center), intends to address questions about RCA.

If you’re an ACPA contractor member and did not receive the survey, please contact Bill Davenport (bdavenport@acpa.org | 847.423.8703).   Want to know more about the survey and why it’s important?  Please contact Leif Wathne (lwathne@acpa.org | 202.638.2272)

Meeting Sharpens Focus on PEMs

Performance engineered mixes (PEM) were the focus of a two-day meeting at ACPA headquarters in Rosemont on Feb. 27 and 28.

Members of the Transportation Pooled Fund PEM Technical Advisory Committee (TAC) discussed the need and vision for the program, the strategy, and other specifics of the program.   FHWA, state highway agencies, and industry presented perspectives and updates, with Jerry Voigt representing contractors and other ACPA members’ interests.  Group discussions and other business, including future meetings and other events of interest were also on the agenda for the second day.

One of the goals for the program is for agencies to specify and contractors to deliver durable concrete pavements every time.   The program is based on measuring and controlling the concrete mixture around engineering properties that relate to performance, according to information produced by the CP Tech Center.

CP Tech Center Names Smith as Associate Director

The National Concrete Pavement Technology Center (CP Tech Center) has named Gordon Smith, P.E., as an Associate Director. 

He has been involved with the CP Tech Center since the late 1990s, and has served as a board member throughout its existence.  He also played key roles in the Center’s founding and in building its long-term partnerships with the Iowa Department of Transportation and industry.

Smith was also involved when the American Concrete Pavement Association and Portland Cement Association allied with the Center as partners in 2005. Joining the CP Tech Center as an associate director seemed like a natural next step for Smith, according to an announcement from the CP Tech Center.

“I am truly looking forward to working with their highly-regarded staff on a more formal basis, offering my knowledge of the industry and our product in the never-ending quest for excellence in the art and science of concrete pavement design, materials, construction, and performance,” Smith said.

He brings almost 45 years of experience with concrete pavements and related products to the table, including 31 years with the Iowa Concrete Paving Association (ICPA) as its president and 16 years as executive director of the Iowa Ready Mixed Concrete Association (IRMCA).

This experience will help him continue to strengthen relationships between the CP Tech Center and its partners and customers in industry and state and federal agencies across the country.

“My vast experience in concrete pavement construction and technology and demonstrated success in building and maintaining strong relationships that culminate in cooperative ventures and accomplish common objectives are the greatest assets that I can offer the CP Tech Center.”

Working alongside Steven Tritsch, P.E., the Center’s other associate director, Smith will work on initiatives related to recycling, concrete overlays, pavement preservation, and other emerging technologies.  A significant portion of his time will be dedicated to the advancement of performance engineered mixtures through a state DOT pooled fund study supported by the Federal Highway Administration.

By working with multiple departments of transportation, industry leaders, and universities including Iowa State, Oregon State, and Oklahoma State, Smith will coordinate research and promote technology transfer.

“It is no secret that Iowa has a long, established history of using concrete as a primary paving material for the construction of state and county roads, streets, airport runways, and bridges,” Smith said.

The advancement of concrete pavement technology and educational outreach to agencies and practitioners has been an integral part of Smith’s entire career with the ICPA and IRMCA, and will continue in his work at the CP Tech Center.
