As part of the second Strategic Highway Research Program (SHRP2) program’s Project R21, a technology showcase was held on January 31 in Burbank, Calif. The focus of the showcase was two-lift concrete pavement construction, and the event drew roughly 70 people representing industry and the public sector.
As a lead state for implementation of SHRP2 R21 technologies, Caltrans, along with Federal Highway Administration, co-sponsored the showcase. The event began with a technical program featuring several agencies’ experience with two-lift concrete paving (including Caltrans, the Illinois Tollway, Minnesota DOT, Tennessee DOT, Texas DOT, and Virginia DOT), followed by a field visit to an ongoing two-lift paving project on Interstate 210 near Montrose, CA. Leif Wathne, ACPA Executive Vice President, was on hand for the event and provided insights on the technology during the discussions.
The project involves a 12-in. thick jointed-plain concrete pavement comprised of a 8-in. bottom lift and a 4-in. top lift. The bottom lift features two separate concrete mixtures, one with reduced cement content and one with recycled concrete aggregate.
About Project R21
Project R21 involves the development of design and construction guidelines for new composite pavement systems, including concrete pavements placed in two-lifts using a wet-on-wet process. Two-lift concrete pavements are said to provide significant potential benefits, including improved surface characteristics, reduced agency costs, lower energy costs, and reduced environmental impacts
Save the Dates for TCC Legislative Fly-In
- Thursday, 09 February 2017 09:54
ACPA is encouraging members and affiliates to save the dates for the 16th annual Transportation Construction Coalition fly-in, scheduled for May 17 through 18 in Washington, D.C.
This year’s event is particularly well-timed in view of the President Donald J. Trump’s infrastructure initiative. The construction industry’s involvement in the development of the plan, as well as enactment by Congress, will be critical to success.
Also, while the “Fixing America’s Surface Transportation Act,” or FAST Act, authorized funding through FY 2020, additional revenue will be needed to support future program growth. It is for this reason that the Administration and Congress must hear from industry that any infrastructure proposal must address the long-term solvency of the Highway Trust Fund.
About the Fly-In
The two-day event begins with a legislative briefing, where officials from Capitol Hill and the Administration will present policy and funding proposals being considered. A reception on the evening after the briefing will provide participants with an opportunity to network with industry peers and members of Congress and their staff.
Participants also will receive briefing materials on key industry priorities to use during meetings with elected officials and their staffers on the second day.
This event will be held at the Hyatt Regency Washington on Capitol Hill, 400 New Jersey Avenue, NW, Washington, D.C. To make reservations, please call 888-421-1442 or 202-737-1234. The room rate is $329 per night; registration cut-off date is April 17.
Event registration details will be available soon, and will be emailed to members and posted on ACPA’s website.
ACPA to Participate in Trade Delegation Program
- Wednesday, 08 February 2017 18:28
ACPA will participate in a Special American Business Internship Training (SABIT) program on highway and roadway construction later this month.
ACPA Executive Vice President Leif Wathne will make a one-hour presentation on concrete pavements to a delegation of approximately 20 officials representing road-building interests in Azerbaijan, Georgia, Kazakhstan, Kyrgyz, Moldova, Russia, Tajikistan, Turkmenistan, and Ukraine.
This program is aimed at providing training to mid- and senior-level industry and State officials who are involved in highway and roadway construction in the Commonwealth of Independent States and Georgia.
ACPA has participated in similar programs on three occasions since 2007. In addition to being a good technology transfer opportunity, the program also allows ACPA to cite member companies involved in technology development and product sales in global markets.

ACPA sent a letter congratulating the Honorable Eileen Chao, recently confirmed as the 18th Secretary of Transportation.
Co-signed by ACPA President & CEO Jerry Voigt and Executive Vice President Leif Wathne, the letter expresses congratulations on behalf of the ACPA members, while also signaling the Association’s willingness to work with the Secretary and her staff. The letter also pledges to continue building on strong relationships with the Federal Highway Administration, Federal Aviation Administration, and other agencies and offices within the Transportation Department.
ACPA has a long history of working closely with senior Transportation Department officials, as well as officials of the subset agencies within the Department. ACPA senior staff and members also have testified before Congress on policy and funding matters that historically have positively impacted programs and funding at both the federal and state agency levels.
Make Plans to Attend Two-Lift Concrete Pavement Showcase

ACPA members, chapter/state affiliates, and members of the media are invited to attend a technology showcase for two-lift concrete pavements on Tuesday, January 31 in Burbank, Calif.
As the lead state for implementation of R21 technologies, Caltrans, in conjunction with the FHWA, is sponsoring the showcase, which will include a technical program featuring several agencies’ experience with the technology, followed by a field visit to a nearby two-lift paving project on Interstate 210. The project is a 12-in. jointed-plain concrete pavement comprised of a 8-in. bottom lift and a 4 in. top lift. The bottom lift features two separate mixes, one with reduced cement content and one with recycled ccncrete aggregate.
About Project R21
Project R21 developed design and construction guidelines for new composite pavement systems, including concrete pavements placed in two-lifts using a wet-on-wet process. The pavement is said to provide significant benefits, including improved surface characteristics, reduced agency costs, lower energy costs, and reduced environmental impacts.
Details about the technical program and technology showcase, along with hotel registration details at the Los Angeles Marriott Burbank Airport Hotel, are included in an event flyer. Click here to download the flyer.
The showcase is being held in conjunction with the FHWA Expert Task Group on Precast Concrete Pavement, which will meet February 1 at the same venue. For additional information, please contact Shiraz Tayabji, Ph.D., P.E., at firstname.lastname@example.org.
