Concrete Pavement University: A Closer Look

For more than a decade, one of the popular features of the ACPA Annual Meeting every year  has been “Concrete Pavement University” (CPU).  Our unique education, training, and tech transfer program lineup for the upcoming 56th Annual Meeting will once again include a content-rich series of keynote speeches and presentations.  Here’s a closer look:

On Wednesday, December 4, our program will begin with a  CPU Opening Plenary Session, from 3:30 p.m. to 5:00 p.m.  Keynote speakers and topics include:

  • AASHTO’s Perspectives on the Future of the U.S. Highway Program – Jim Tyman, Executive Director; American Association of State Highway and Transportation Officials (invited) 
  • Federal Highway Administration Outlook – Brian Fouch, PE, Director; Office of Preconstruction, Construction, and Pavements, Federal Highway Administration, and  
  • The Value of Competition Between Industries: A Former DOT Secretary’s Perspective – Tom Smith, PE, Former Secretary, West Virginia Department of Transportation

On Thursday, December 5, the 11th annual CPU program will continue after the ACPA distinguished service awards & recognition breakfast.  Participants can select from eight interesting and informative concurrent CPU technical sessions. Breakout sessions 1, 3, 5 & 7 form a contractor/construction track. Breakouts 2, 4, 6 & 8 form a track of general interest to all.

Don’t miss it!  To be part of the information-packed program, be sure to register as soon as possible for ACPA’s 56th Annual Meeting. Our one-stop event and hotel registration is http://2019meeting.acpa.org/.  To reserve a room at the Marriott at a discounted rate of $189/night, follow this reservation link or visit the event website.  ACPA members are eligible to receive a 20% discount off any registration ticket type, including those for your spouse and guests for whom you are paying.

Webinar Covers Life-Cycle Assessment

There’s still time to register for an informative webinar covering the fundamentals of Life-Cycle Assessment (LCA), which is scheduled for Thursday, August 22 from Noon to 1:30 (CDT) | 1:00 to 2:30 p.m. (EDT).

LCA is a technique to assess environmental impacts associated with all the stages of a product’s life. In the context of a concrete pavement’s life, this involves deriving the raw materials, processing/manufacturing, placement, use, repair and maintenance, and disposal or recycling/reuse.

Co-sponsored by the International Society for Concrete Pavements (ISCP) and ACPA, the program will be presented in two parts.  The “Basics of LCA for concrete pavements,” will be presented by Eric Ferrebee, P.E., Technical Services Engineer, ACPA. “Concrete pavement LCA examples,” will be presented by Tim Smith, P.Eng., Senior Director, Built Environment, Transportation and Public Works for Cement Association of Canada & Director-ISCP.  

 ACPA members are eligible for individual and group registration discounts. The webinar is free of charge to government employees. For additional information, please follow this link: http://www.acpa.org/upcoming-webinars-meganars-and-workshops/.  

FHWA Offers Pavement Restoration Checklists

In the resource spotlight this week is the National Concrete Pavement Technology Center’s (CP Tech Center’s) series of updated and new pavement preservation  checklist.

Originally developed by the Federal Highway Administration (FHWA) in 2002, the preservation checklists provide excellent information on innovative pavement preservation techniques. Designed to guide state and local highway preservation/maintenance and inspection staff, the checklists provide useful information to contractors and others with an interest in concrete pavement preservation, repair, and restoration. 

Checklist topics include the following: 

• Joint and Crack Sealing • Full-Depth Repair
• Diamond Grinding • Cross-Stitching
• Dowel-Bar Retrofit • Longitudinal Diamond Grooving
• Partial-Depth Repair  

 

The complete list of 2019 and 2002 checklists may be found on FHWA’s pavement preservation resource website. The CP Tech Center also includes a link to the resources on its curated online library of pavement preservation resources. 

 

Panel Evaluates Pavement-Vehicle Interaction

An FHWA technical review panel (TRP)* is studying various Pavement-Vehicle Interaction (PVI)** models —including two from MIT—to assess the role the models can play in determining vehicle operating costs and evaluating excess fuel consumption based on roadway conditions.

One of the goals is to determine the compatibility of PVI models with traditional economic models that agencies use for highway and roadway investment.  The panel also plans to study and resolve  gaps between the PVI and economic models, and all of this is aimed at ultimately influencing factors that can improve pavement sustainability.

An initial web meeting last week began with a discussion of both the study and meeting objectives, literature review, and other details, including comments about the various PVI models currently available. In opening remarks, the panel acknowledged a comment that none of the current PVI models has been perfected to date.

“No model is perfect,” says Leif Wathne, ACPA Executive Vice President, “But that doesn’t mean it’s not useful.  These models are context sensitive and there are uncertainties, but there are ways to handle uncertainty. We need to use the models as best we can to inform decision making.”

Leif, along with ACPA Chairman Jim Mack (CEMEX) represent the concrete pavement industry on the panel.  Jim says awareness about PVI has increased significantly and adds this has become an increasingly important sustainability factor to the roadbuilding community.

“The roadbuilding community has gained a greater understanding and appreciation for the value of PVI modeling than when the industry and MIT first presented it in 2012,” he says.  Today PVI is widely seen as an important use-phase sustainability benefit, and in fact is one of the major factors in use-phase sustainability consideration.  Use-phase benefits are often significantly more impactful than other environmental factors such recycling and reuse, particularly for heavily trafficked corridors.   

“None of this would have likely happened had the cement and concrete industry not invested in itself to research, advocate and support PVI and other sustainability research and technology,” Jim says,

The work of the TRP is particularly important because of the current situation with limited funding, which impacts everything from research to staffing among agencies.

“We’re currently in a period of constrained resources,” Jim says, “And yet, industry is being asked to address issues that we’ve never had to deal with in the past.” He points to the ACPA’s VISION2040 initiative, which is looking closely at disruptors such as driverless vehicles, in-road magnetic induction, smart highways/roadways and other technologies that will increasingly affect how infrastructure investment decisions are made by agencies.

“PVI goes far beyond traditional cost factors and pavement type selection decisions used historically,” Jim says, adding, “This initiative is really about improving the quality of information needed to make the best and most informed decisions possible.  This is not just about fine-tuning the approach to cost and pavement-type selection, and in fact, decisions among highway and roadbuilding agencies will increasingly be made long before pavement type is considered.”

“As we look ahead, industry will continue efforts to learn more about PVI and its role in highway construction and continue supporting our agencies with solutions that offer exceptional performance, longevity and value, and of course, sustainability benefits,” Jim says.

* The TRP is being led and facilitated by the FHWA’s Turner-Fairbank Highway Research Center, Engineering & Software Consultants, Inc, The Transtec Group, Inc.  The TRP is comprised of three state highway agency officials, two members of academia, representatives of Argonne National Laboratory and the National Institute of Standards and Technology, and representatives from the concrete and asphalt pavement industries. 

** PVI is a concept that looks at the interaction between a vehicle’s tires and the roadway surface on which it is driving, according to MIT, which adds, it is also known as rolling resistance.
