PCA/ACPA Paving Webinar Spotlights Caltrans Research, FAA Specs
- Tuesday, 09 July 2019 07:09
The next PCA/ACPA monthly paving call is scheduled for Friday, July 12, at 10 a.m. (Central) 11 a.m. (Eastern). This month’s webinar will feature:
- An overview of the upcoming Promoters’ Forum, which is designed for local promoters to learn about the latest promotion techniques and resources available from national organizations and from other promoters. (Speaker: Alpa Swinger, PCA)
- A Caltrans-supported research project, which is examining the potential use of Portland Limestone Cement/Ordinary Portland Cement+Limestone (PLC / OPC+LS) made with clinkers that are historically type II/V. (Speaker: Dr. Jason Weiss, Oregon State University)
- A presentation that will highlight some of the impacts ACPA and the concrete industry had on the recently updated Federal Aviation Administration airport construction guide specifications, including a new full-depth reclamation specification and other positive changes that will help promote the use of concrete pavements at general aviation airports. (Speaker: Gary Mitchell, ACPA)

ACPA Participates in TRB Concrete Pavements Meeting
- Monday, 08 July 2019 13:20
Eric Ferrebee of ACPA participated in the Transportation Research Board’s recent Mid-Year Meeting for the Concrete Pavement Design and Construction Committees in Orlando, FL.
The Florida Chapter hosted the meeting and welcomed Florida DOT, Alabama DOT, and FHWA personnel, as well as other transportation experts. In addition to chair reports, the meeting also included TRB staff comments, as well a presentation on designing long-life concrete pavements (by Rich Rogers, Texas Cement Promotion Council), an FHWA concrete pavement update (by Tom Yu, FHWA), Florida DOT’s concrete pavement test road (by Jamie Greene from Florida DOT), and an in-depth analysis of concrete pavement cracking (by Georgene Geary GG&GA).
The group also heard presentations about the I-4 Ultimate Project , which they also toured. At $2.3 billion, this is one of the most expensive projects the Florida DOT has ever done. The project reconstructs a 20-mile section of I-4 through Orlando and also creates express lanes through the corridor.
Professors’ Seminar Begins July 22
- Monday, 08 July 2019 10:32
The PCA Education Foundation’s Professors’ Workshop is schedule for July 22 through 26.
The event this year will be held at the American Concrete Institute (ACI) world headquarters in Farmington Hills, MI. The Professors’ Workshop is designed for professors and other instructors in civil engineering, architecture, architectural engineering, materials science, and construction management programs.
The program provides the academic community with tools to engage students in the latest developments in concrete design, construction, and materials.
Eric Ferrebee, ACPA Technical Director, will be among the prominent, nationally-known faculty and industry representatives who will present technical information, trends and other information. Eric will be teaching Joint Layout and Design and Pavement Thickness Design.

ACPA to Cosponsor & Exhibit at CONEXPO
- Monday, 08 July 2019 06:44
ACPA this week formally confirmed its plans to exhibit at CONEXPO-CON/AGG. Billed as North America’s largest construction trade show, the event is scheduled for March 14-20 at the Las Vegas Convention Center and surrounding area. The trade show and educational/tech transfer forum is held every three years.
Registration officially opens on July 23. ACPA is pleased to serve as a co-sponsor of the show and, along with other sponsoring associations, will actively promote attendance and participation in the event.
CP Tech Center Releases RCA Report
- Tuesday, 02 July 2019 10:37
The CP Tech Center has released a report summarizing key findings of a research project aimed at gaining a better understanding of where and how extensively concrete pavement recycling and recycled concrete aggregates (RCAs) are being used in the United States.
“Recycled Concrete Aggregate Usage in the US” is a 38-page report that describes the two-phase benchmarking research project, origins of concrete pavement recycling and factors driving the need to recycle and reuse RCAs.
The four-color publication begins with an introduction and background information, details about the opportunities for sustainable material practices in concrete pavement construction and rehabilitation, and details from the survey on RCA use in roadway applications. The report also includes conclusions and recommendations, as well as details about ACPA’s plans for tracking data and working to train members (and support the FHWA and state DOTs) in specification and policy development focusing on the beneficial use of existing concrete pavements.
Although the survey was not funded by the Federal Highway Administration (FHWA), the results have helped guide the work on technology transfer under one of their cooperative agreements. The results have been made fully available to support the FHWA’s goals of supporting more sustainable pavement technical solutions. ACPA member contractors were among those who assisted the research by participating in surveys presented by ACPA.
