New Resources Address Bridge Deck Cracking
- Tuesday, 17 March 2020 11:53
New resources from the CP Tech Center take aim at the issue of bridge deck cracking, as reported in the spring issue of the NC² News, the consortium’s quarterly newsletter.
One resource is the new NC² Moving Advancements into Practice (MAP) Brief,”Extended-Life Concrete Bridge Decks Utilizing Internal Curing to Reduce Cracking—Results from Ohio DOT Field Trial,” is now available from the NC² Resource Library.
The 8-page brief includes a brief introduction, which details common causes and contributing factors. The publication also includes a section on internal curing, concrete mixtures and placement considerations. Additionally, the publication includes sections on performance monitoring, predicting service life, life-cycle cost analysis, and Ohio’s plans to use lightweight fine aggregates and specialized mixture designs to mitigate cracking.
In addition to the MAP brief, the CP Tech Center is drawing attention to resources covering bridge deck construction and related issues. To access the information, click here. When the web page appears, look for the search field and enter “bridge deck” to see recent resources.
The CP Tech Center is also encouraging engineers and other professionals to check out recent questions, included one added by the WV DOT, in the NC² States’ Q&A Listserv. The Listserv allows member states of the TTCC Pooled Fund to poll other member states regarding specifications, materials, construction, research, or other concrete paving issues.
Colorado/Wyoming Hosts Successful Workshop
- Tuesday, 17 March 2020 05:21
The Colorado/Wyoming Chapter’s annual concrete pavement workshop last week drew about 200 professionals together to hear an all-star line-up of experts who presented on a wide range of important and timely topics.
Angela Folkestad, Jerry Voigt and Steve Harelson (CDOT Chief Engineer) delivered the opening remarks. Dr. Jeremy Gregory of the MIT Concrete Sustainability Hub presented “Innovative Solutions for Improving Concrete Sustainability,” and Jerry Voigt presented “Shaped by Concrete: Enhancing Sustainability in the Cement and Concrete Industry,” drawing on resources from ACPA and from PCA’s new “Shaped by Concrete campaign.” Amy Brooks of Castle Rock Construction and Bob LaForce, Yeh and Associates, also described ways of “Achieving Sustainability Goals through Concrete Pavement Longevity.”
“The presentations were insightful, and we hope that they will lead to additional discussion in the coming months,” Angela says, adding, “The presenters also provided information that gave participants new ways of looking at sustainability.” Breakout sessions were held in the late morning and early afternoon, and covered design, construction, maintenance, materials and asset management/maintenance.
Angela noted there was particularly strong interest in two airport tracks, one covering sustainability and the other covering concrete pavement specs. Gary Mitchell, along with representatives from the FAA, Colorado DOT Aeronautics, Denver International Airport and three engineering firms were also involved in the sessions.

Pennsylvania Chapter Offers Videotaped Presentations
- Monday, 16 March 2020 12:56
Editor’s Note: As a follow-up to our February 24th story about the ACPA Pennsylvania Chapter’s successful Pennsylvania Concrete Conference, we’re presenting details about the presentations the chapter is offering.
Presentations conducted and videotaped at this year’s Pennsylvania Concrete Conference are now all available online at: https://go.acpa.org/acpa-penn-concrete-conference. These talks cover a wide range of business and technical topics related to concrete pavement and other concrete products.
The ACPA Pennsylvania Chapter began videotaping conference presentations ten years ago. Faced then with losing many of their attendees because of a forecasted storm of the century (that never came), and speakers already in Harrisburg or en route, the chapter quickly made arrangements to videotape the talks.
It worked well, and the recordings have subsequently allowed PennDOT staff whose travel is often restricted because of funding challenges (and now because of the coronavirus) to be able to benefit from the presentations made at the conference. Many of these presentations remain as excellent learning tools, and all remain accessible at https://www.longerlifepavement.com/conference/.
National Concrete Consortium Postpones Spring Meeting
- Monday, 16 March 2020 12:15
The Spring 2020 National Concrete Consortium, originally scheduled for this month, has been postponed. This followed similar actions associated with the COVID-19 pandemic, accoding to the CP Tech Center, which manages registrations.
Those who have made plans to participate in the meeting are asked to cancel reservations with the Embassy Suites Nashville Airport by calling 1.800.Embassy or 1.800.362.2779. The CP Tech Center is checking calendars and working with the Nashville hotel in hopes of rescheduling the meeting. In the interim, registration fees will be refunded.
ACPA at ConExpo-Con/Agg
- Tuesday, 10 March 2020 05:54
Concerns about the COVID-19 virus, politics and the economy gave way to the will of more than 100,000 participants in ConExpo-Con/Agg, North America’s largest construction trade show.
Show organizers acknowledged some exhibitor and registrant cancelations, but indicated last minute registrations brought the totals up to more than 100,000 participants and resulted in more than 2,500 exhibits spanning over 2.6 million sq. ft.
Scott Mueller and Bill Davenport are representing ACPA, which is located in the Grand Lobby, booth GL32208. We’re encouraging members and others to stop by this week to discuss programs and services, and of course, all aspects of concrete pavement research, design, construction and rehab. The Grand Lobby is the area between the North and Central Halls of the Las Vegas Convention Center.
By popular demand, we’re doing another trivia contest, where booth visitors will have an opportunity to test their knowledge of concrete and concrete pavements, as well as music.
