ACPA Briefs Eurasian Transportation Leaders

A group of 20 industry professionals from Eurasia heard about concrete pavement from Leif Wathne in Washington, D.C. on February 27. 

The meeting briefing was part of the U.S. Department of Commerce’s Special American Business Internship Training or SABIT, as part of its  road construction program.  This marks the sixth time ACPA has participated in this program since 2007. 

Among the topics Wathne discussed were PavementDesigner.org, Wikipave, and details about ACPA strategies and programs.   

MIT Webinar Explains Importance of Albedo

An important sustainability feature of concrete pavements is their high albedo.  The topic of albedo and its impact on global warming are the subject of a webinar scheduled for Thursday, February 15, at 11 a.m. (EST) | 10 a.m. (CST).

Albedo, Climate, and Urban Heat Island,” will be presented by CSHub Executive Director Dr. Jeremy Gregory.  The webinar will also discuss an approach developed by CSHub researchers to quantify the impacts of changes to pavement albedo, and then to translate those changes into global warming potential. This webinar also report on results from recent studies on the topic.

This webinar is free and open to the public, but advance registration is required. For more information and to register, visit: calendar.mit.edu/event/cshub_albedo.

Webinar is Latest Outreach on PavementDesigner

Following the official external launch of PavementDesigner.org on January 8, the sponsoring associations* are continuing the outreach, education and promotional efforts with a webinar to present the broad-based pavement design community with an overview of free web-based concrete pavement design resource.  ACPA’s Eric Ferrebee will lead the webinar with support from NRMCA and PCA.  
The webinar is scheduled for Wednesday, February 28 at 1 p.m. (Eastern) \ Noon (Central.  There is no cost for this 90-min.webinar, but registration is required at:  https://attendee.gotowebinar.com/register/9041644043927173634 .   Please note this registration limited to 500 groups and individuals.   Registration is offered on a first-come/first-served basis.

About the Webinar
This 90-minute webinar describes PavementDesigner.org, a free, web-based pavement thickness design platform, which was created for city, county, and consultant engineers, academia, or anyone involved in design of roadway, industrial, and parking area pavements.

Learning objectives are to:
• Create or enhance a basic understanding of the history of concrete pavement design
• Inform of the evolution and development of PavementDesigner.org
• Demonstrate the three-step approach to PavementDesigner.org
• Demonstrate features and benefits
• Present and discuss sample pavement designs for various applications/facilities
• Provide recap and question/answer opportunities

* Primary sponsors are the American Concrete Pavement Association (ACPA), the Ready Mixed Concrete (RMC) Research & Education Foundation, and the the Portland Cement Association (PCA).  Additional funding and support came from the RCC Pavement Council.   The RMC Research and Education Foundation is affiliated with the National Ready Mixed Concrete Association.   

Concrete Pavements Prominent at SWIFT Conference

ACPA was among several concrete pavement industry organizations participating in the 2017 Summer Winter Integrated Field Technologies (SWIFT) conference and trade show, held recently in Halifax, Nova Scotia.

Prior to the formal meeting of the Canadian Airfield Pavement Technical Group (CAPTG), a special workshop was held to address, “How to Design Sustainability Into Airfield Pavements.”

Workshop speakers included Gary Mitchell, P.E., ACPA’s Vice President of Airports and Pavement Technology, and Peter Taylor, Ph.D., P.E., Director of the National Concrete Pavement Technology Center, an ACPA technology partner.  Mitchell presented on concrete pavement recycling practices and technologies. Taylor presented on the importance of the life-cycle perspective and performance-engineered mixtures.

The formal SWIFT meeting followed the workshop and included moderated discussions and presentations.  Industry officials presented on several topics during Tuesday and Wednesday sessions.  These included: 

  • Stringless paving by ACPA’s Mitchell, as well as several ACPA members and technology partners.
  • Runway grooving for improved braking performance and directional control by John Roberts, Executive Director of the IGGA/ACPA Concrete Pavement Preservation Partnership and John Depman, P.E., Senior Estimator, Penhall Company. 
  • Rapid airfield repair using precast by Chris Olidis, P.E., Principal Engineer, Applied Research Associates, an ACPA member.
  • Optimized concrete pavement design by Robert Rodden, P.E., Lead Engineer, PNA Construction Technologies, an ACPA member. 

Also, moderating the Wednesday technology track was Guillaume Lemieux, Director, Markets and Technical Affairs, Cement Association of Canada, an ACPA affiliate.

SWIFT offers the airport community the opportunity to gather and learn about new pavement design, construction, evaluation and maintenance techniques; materials; chemicals; systems; and equipment available to keep airports safe and operational while addressing any challenges, at minimal cost, during all seasons.

Open House to Showcase Next Generation Concrete Surface

In the early part of the 2000’s, the concrete pavement industry was challenged to address the issue of noisy pavements.   With a significant investment by ACPA, The International Grooving & Grinding Association (IGGA), and the Portland Cement Association, an extensive research and testing program was undertaken to develop a quiet, safe and durable concrete surface texture. 

The outcome of this effort was the developments of the Next Generation Concrete Surface (NGCS).  NGCS was developed under the auspices of ACPA, and with research and testing by the IGGA/ACPA Concrete Pavement Preservation Partnership (CP3), Purdue University, and the Minnesota DOT’s MnRoad facility, along with testing and implementation support from industry, agencies/owners, Chapter/States, and others interested parties.

Ten years after the technology was first developed, the city of Houston, with approximately 3M SY of this quiet pavement surface, holds the distinction of being the largest single user of NGCS technology in the world. 

On November 15, transportation agency officials, industry officials, members of academia, and other interested parties are cordially invited to participate in the “I-10 NGCS Ride Experience Open House,” in Houston.  

The special event will be held from 10 a.m. to 12:30 (CST) at the Texas DOT’s Houston Headquarters, located at 7600 Washington Ave. 

The day begins with presentations in the District’s conference room, after which, participants will have an opportunity to experience the NGCS surface on a chauffeured drive along a section of I-10.  A luncheon also will be served.  Also, an equipment demonstration will allow participants to view commercial diamond-grinding equipment, along with samples of various types of diamond-ground pavement textures.

The event is jointly sponsored by the IGGA/ACPA CP3, Cement Council of Texas, Texas Concrete Pavement Association, American Concrete Pavement Association, CEMEX, Penhall Company, and the Texas DOT. 

Attendance is free of charge, but advance registration is required.   To register, please contact Larry Scofield at lscofield@pavement.com.

More About NGCS
Since its inception, NGCS has gained wide-spread acceptance across the United States and other countries.  Research reports, a report on the development and implementation of the technology, and other technical information may be downloaded online from the websites of ACPA and the CP3.
