ACPA Supports FHWA with Tech Reviews

ACPA technical staff is supporting the FHWA with reviews of technical resources that will be used in the agency’s Pavement Notebook.  ACPA has reviewed (or is currently wrapping up) technical reviews on more than 15 documents.  ACPA members and affiliated Chapter/State execs and promoters, along with PCA and the CP Tech Center have also been called on to offer technical expertise and insights.

Topics of the tech bulletins include:

  • Air Entrainment and Concrete Durability
  • Chemical Admixtures
  • Chemical Deicers and Concrete Pavement – Impacts and Mitigation
  • Concrete Pavement Preservation Treatments
  • Concrete Pavement Texturing
  • Curing
  • Dowel Alignment
  • Field Control of Concrete Paving Mixtures
  • Joint Sealing 
  • Opening concrete Pavements to Traffic
  • Paving Under Adverse Weather Conditions
  • Specifying, Designing, and Proportioning Paving Concrete
  • Stringless Paving 
  • Thin Concrete Overlays
  • Traffic Management

FHWA Offers Resources, Equipment Loans

The FHWA’s Mobile Concrete Trailer (MCT) is offering four, 1-page documents that cover subjects related to concrete pavement mixtures and operations, based primarily on experiences and observations from the MCT.  They include: 

The FHWA also plans to release two new 1-page documents later this spring – one on concrete pavement tining, and another on resistivity testing (in the context of AASHTO’s PP-84 Standard Practice for Developing Performance Engineered Concrete Pavement Mixtures).  As these and other documents are developed, they will be posted on FHWA’s MCT resources page

If you have questions about these one-pagers or the MCT program, please contact Mike Praul at Michael.Praul@dot.gov or 207.512.4917.

ACPA Papers Accepted for International Symposium Proceedings

Four papers developed by ACPA technical staff and members have been accepted for publication in the proceedings of the 13th International Symposium on Concrete Roads.  Topics include:

  • Concrete Pavement Joint Sealing & Filling–A U.S. Perspective … Jerry Voigt and Mark Snyder (Pavement Engineering and Research Consultants-LLC)
  • Development of a Dowel Alignment and Location Guide Specification … Mark Snyder, Jerry Voigt, and Robert Rodden (PNA Construction Technologies)
  • The Future of Concrete Pavement in North America  … Leif Wathne, Jerry Voigt, and Gary Fick (Trinity Construction Management Services, Inc.)
  • Regionalized Life Cycle Assessment Tool for Evaluating Concrete Pavement Alternatives … Eric Ferrebee and Jeff Roesler (University of Illinois at Urbana-Champaign)

 

Concrete Sustainability Hub Meeting Update

Exciting developments at the MIT Concrete Sustainability Hub (CSHub) were the focus of combined Industry Advisory Council/Technical Advisory Group Meetings in Cambridge, MA, on April 3 and 4.

Updates and other presentations focused on pavements and buildings, key components of the CSHub’s research and implementation portfolio, which encompasses science, engineering, economics, and environment.

Just a few of the pavement-related highlights of the meeting included:

  • A presentation by MIT’s Dr. Randolph Kirchain, who described a new probabilistic allocation network-level pavement management model that also takes uncertainty into account. This has great potential to help agencies improve the cost effectiveness of their pavement management strategies in an era of increased focus on performance measures and asset management.
  • An update on the CSHub’s statistical model estimating the impact of inter-industry competition on paving prices. The model demonstrates that increasing inter-industry competition has the potential to significantly lower both asphalt and concrete paving prices.  This can save agencies as much as 10 to 15%.
  • An overview of recent work on quantifying the climate impacts of pavement albedo. This work enables researchers to identify exactly what portions of a urban landscape on which it makes sense to use cool pavements.
  • A preview of MIT’s Phase 3 research & implementation plan, which transitions from research to implementation with a focus on concrete as a solution to ‘big picture’ challenges. A few of the opportunities for concrete pavement-related solutions include: Improving construction industry productivity; improving the ASCE road-condition grades across the nation; and meeting the ASCE Grand Challenge. These are of interest and importance to the concrete pavement industry because they augment or otherwise support key ACPA strategies and program tactics.

The meetings drew professionals from industry and academia, including ACPA members, as well as those representing the ACPA Chapters and CP Tech Center. Leif Wathne represented ACPA as a member of the Pavements Technical Advisory Group.

Reminder: Cement & Concrete Industry Fly-In

ACPA is urging all members and affiliates to participate in the annual Cement & Concrete Fly-In, scheduled for April 24 and 25 in Washington, D.C. Hotel rooms are going quickly, so please make plans as soon as possible.

Why is this event more important than ever?  Elected officials need to hear from industry officials, and the timing is right because of the Trump Administration’s focus on infrastructure investment, as well as reauthorization proposals being developed, now is the time to let elected officials know about our priorities, as well as the need for funding and a durable HTF fix.  Don’t miss this opportunity to hear legislative briefings and to be part of the discussion with Congressional offices and other Federal officials.   

Click here to see the agenda; here to register for the event; and here to reserve a hotel room at the Hyatt Regency Washington on Capitol Hill.
