Meeting Sharpens Focus on PEMs
- Tuesday, 27 February 2018 15:54
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.
Tyler Ley: Having Fun in the Serious Pursuit of Quality
- Sunday, 25 February 2018 03:47
Editor’s Note: For anyone who’s had the opportunity to hear and see Dr. Tyler Ley speak about concrete pavements, it’s easy to see why the Oklahoma State University professor (and 2017 recipient of the Marlin J. Knutson Award for Technical Achievement) has a well-deserved reputation for being passionate about concrete pavements.
Click here to check out the YouTube channel he created to teach people about concrete. He starts with the basics of concrete, then goes on to explain more technical topics, including testing, mixture design, cement manufacturing, admixtures, and durability.
For seasoned professionals, newcomers to the field, students, and others who share a strong interest in concrete pavements, the full video series is worth watching. Although many of the videos include some amusing examples (and some are downright funny!), there’s no mistaking how serious Dr. Ley is in his quest for consistent concrete mixtures and his efforts to improve the quality of concrete pavements.

ACPA Building Stronger Presence in Florida
- Friday, 16 February 2018 04:22
ACPA enjoyed a strong presence at the Florida Transportation Builders Association’s 2018 Construction Conference on Feb. 8 and 9. The event was held in Orlando, Fla., and attracted more than 1,700 attendees.
Leif Wathne discussed ACPA’s VISION 2040 initiative and announced the affiliation of the Florida Chapter-ACPA during his overview of national ACPA activities. Wathne highlighted the association’s technical and promotion objectives and major goals. Wathne also expressed the Association’s excitement and interest in becoming more involved with agencies and industry in Florida, then thanked local Association members for their support of the new chapter.
ACPA Vice Chairman Jim Mack (CEMEX) also spoke at the conference on jointing concrete pavements and how to make them work in intersection applications, a topic identified as a key learning objective of the Florida DOT for its growing concrete paving program.
HMG Welcomes Trump Plan, Urges Funding Solutions
- Wednesday, 14 February 2018 12:44
The Highway Materials Group* (HMG) issued a formal statement welcoming President Trump’s proposal to invest $1.5 trillion in America’s infrastructure. The group views the plan as a strong starting point in on-going discussions for much needed investment, but noted details were still too few.
“The plan needs a reliable pay-for that provides certainty for projects and shores up the Highway TrustFund,” said Jerry Voigt, President and CEO of the American Concrete Pavement Association. “HMG supports a variety of options such as fuel tax increases, vehicle miles traveled and highway freight fees, to name a few. All options should be on the table. We need infrastructure investment now.”
While the group isn’t opposed to privatization playing a role in investment, the group noted that it shouldn’t be the entire story and supports Congress pulling from many competing proposals to return to the certainty once brought from routine authorizations and appropriations bills.
HMG encourages Congress to quickly pass bipartisan legislation that shores up the HTF and improves our country’s communities, commutes and economy.

* The Highway Materials Group is comprised of the American Coal Ash Association, American Concrete Pavement Association, American Traffic Safety Services Association, Associated Equipment Distributors, Association of Equipment Manufacturers, Concrete Reinforcing Steel Institute, National Asphalt Pavement Association, National Ready Mixed Concrete Association, National Stone, Sand & Gravel Association, Portland Cement Association, and the Prestressed/Precast Concrete Institute.
