Have You Registered for ACPA’s Airport Workshop?
- Thursday, 03 October 2019 13:51
There are still seats available for ACPA’s Airport Pavement Design & Construction Workshop, but ACPA is urging those interested in the three-day training event to reserve seats and hotel rooms quickly.
The workshop this year will be held at the Embassy Suites in Fort Lauderdale (FL) from Oct. 22 through 24. Please click here to visit our one-stop website, which includes a registration link, hotel registration link, and updated agenda.
One of the popular highlights of the workshop is straightforward, often spirited discussions about concrete pavement specifications for airports, notably the FAA’s P-501 spec and the UFGS 32 13 14.13 spec used for US Army Corps of Engineers and other Tri-Services projects.
TRIP Report Focuses on Freight Transportation Issues
- Thursday, 03 October 2019 12:32
The Road Information Program (TRIP) today released a report called “America’s Rolling Warehouses: Opportunities and Challenges with the Nation’s Freight Delivery System.”
The report examines the ability of the nation’s freight transportation system to accommodate the growing demand for freight movement efficiently and safely in spite of significant issues. Some of the top issues include inadequate transportation capacity, a lack of funding for needed improvements to the freight network, a shortage of drivers, and consumer demands for faster delivery.
The report ranks the states with the greatest amount of freight shipped to or from sites in their state, states with the highest share of Interstate vehicle miles of travel by combination trucks, states with the largest average annual number of large truck fatalities, and states with the largest projected increase in freight movement between 2016 and 2045.
TRIP’s report also identifies the nation’s 20 worst freight highway bottlenecks and concludes with a series of recommendations to improve the nation’s freight transportation system. TRIP released the report this morning and is supporting the public affairs initiative with national and state media work. Click here to download a copy.
TRIP Executive Director Will Wilkins will be addressing this and other issues at ACPA’s upcoming 56th Annual Meeting, which is scheduled for December 3 through 5, in New Orleans. TRIP is a national transportation research nonprofit, based in Washington, DC.
Associations Express Support for Research Funding
- Thursday, 03 October 2019 11:56
The chief executives of the American Concrete Pavement Association (ACPA), National Asphalt Pavement Association (NAPA) and Portland Cement Association (PCA) today issued a joint statement welcoming the inclusion of funding for increased airfield pavement research in S. 2520 and H.R. 3055 (Division E) appropriations bills for fiscal year 2020. The House passed H.R. 3055 in June, and the Senate will consider S. 2520 as it works through the appropriations process over the coming weeks. Click here to see the joint statement.
Gerald Voigt, P.E. (ACPA), Audrey Copeland, Ph.D., P.E. (NAPA), and Michael Ireland (PCA) released the statement, which was sent to the media and shared with members of the three associations. Letters were send to Senate Appropriations Committee members, also expressing support for the research provision.
The research funding, if approved in the final appropriations bill, would be used to support a research provision included in the FAA Reauthorization Act of 2018 Sec. 744 “Research and deployment of certain airfield pavement technologies.” The provision is similar to the Accelerated Implementation and Deployment of Pavement Technologies (AID-PT) first included in the Moving Ahead for Progress in the 21st Century Act (MAP 21), creating both a mechanism and funding for the delivery of pavement technology. AID-PT was also included in the Fixing America’s Surface Transportation (FAST) Act, and provides funding through 2020.

Group Urges Senate Leaders to Support Timely Reauthorization
- Thursday, 03 October 2019 11:08
The Infrastructure Working Group (IWG) sent a letter to Senate Majority Leader Mitch McConnell (R-KY) and Minority Leader Charles Schumer (D-NY) urging bipartisan action to address our nation’s long-standing infrastructure deficit.
“As this challenge persists and worsens,” the group wrote, “we encourage you to move a long-term, robustly funded surface transportation reauthorization ahead of the September 30, 2020 deadline. The group cited the imperative to avoid costly delays that slow construction schedules and make important projects more costly and more difficult to complete.”
The letter continued, “Substantial and long-term investments in all kinds of infrastructure are needed to expand our economy, grow jobs and compete globally. We appreciate strong bipartisan support for various infrastructure initiatives over the years and hope momentum recently initiated by the Senate Environment and Public Works Committee can lead to a successful, bipartisan surface transportation reauthorization.”
Led by the National Association of Manufacturers and the Associated General Contractors, the IWG exists to unite a diverse range of trade associations and build support for infrastructure investments. The IWG works to unite the common interest of support for infrastructure investment among a diverse range of industry organizations.

Publication Explains Concrete Test Method
- Thursday, 03 October 2019 06:44
The FHWA Mobile Concrete Technology Center (MCTC) is offering a one-page tech transfer document that provides some observations on a simple, inexpensive field testing concrete & cementitious material hydration. Hydration, of course, creates exothermic chemical reactions, which can be monitored by measuring the total heat generated over time.
“Monitoring Concrete Consistency using Semi-Adiabatic Calorimetry” descibes a test method that can monitor batch-to-batch consistency of concrete mixtures. The test works by casting a standard concrete cylinder, then placing it in the calorimenter, recording the time-temperature curve (or heat signature), then comparing the curves of other samples from the same mixture.
Calorimeters are described as effective tools during mix design to determine potential material incompatibility or optimal dosages/sequence of addition of admixtures. They can be used to determine setting times and saw cut times in lieu of physical testing. Semi-adiabatic calorimeters can also be used as a quality control tool to monitor variations in the sources, quantities, and chemistry of portland cement, supplementary cementitious materials, and chemical admixtures during concrete production.
