Next Gen IMCP Manual Now Available

The 2nd edition of the Integrated Materials and Construction Manual for Concrete Pavements (IMCP) manual is now available.  

The next generation publication has been updated to include the latest innovations and practices, including a chapter on sustainability, updates on test methods to evaluate concrete mixtures, and other current practices that have evolved in the years since the first edition was published in 2006.  Like the first edition, the 2019 edition is well organized in 10 tabbed chapters, complete with photos, technical drawings and other illustrations.  Tables and “popout” sub-sections provide snapshot descriptions and other useful details. 

The publication is a “must-have” reesource for contractors, QC and QA personnel, materials and equipment suppliers, and anyone with an interest in concrete materials, construction practices, and the production of quality pavements. According to the CP Tech Center, the updated publication is designed to help the reader:

  • Understand concrete pavements as complex, integrated systems.
  • Appreciate that constructing a concrete pavement project involves several discrete practices that interrelate and affect one another in various ways.
  • Implement technologies, tests, and best practices to identify materials, concrete properties, and construction practices that are known to optimize concrete performance.
  • Recognize factors leading to premature distress in concrete and learn how to avoid or reduce them.
  • Quickly access how-to and troubleshooting information.

ACPA staff, members and affiliates were key contributors to the 2nd edition of the IMCP.  Contributors include: Angela Folkestad, Colorado/Wyoming-ACPA; Allen Johnson, W.R. Grace & Co. (ret.); Kevin Klein, GOMACO Corporation; Jim Mack, CEMEX USA; Chris Poe, AJAX Paving; David Suchorski, Ash Grove Cement Company; and Leif Wathne, ACPA. Many ACPA technical publications and other resources were used and cited as references to the new edition.

Training Event Focuses on Pavement Preservation

Eric Ferrebee, ACPA Technical Service Director, and Steve Tritsch, Associate Director of the CP Tech Center, represented the concrete pavement industry at the Pavement Preservation Summit in Puerto Rico this week. Sponsored by the FHWA, the program began with remarks by officials from the FHWA, as well as local agency and industry officials.

The first day of the two-day event included concrete and asphalt tracks. Eric and Steve participated as presenters in three concrete-related tracks, with Eric covering diamond grinding and grooving; load-transfer restoration and cross stitching; and partial-depth concrete pavement repairs.  Steve covered joint resealing and crack sealing; full-depth concrete pavement repairs; and slab replacement. The summit, held at the College of Engineers and Surveyors of Puerto Rico in Hato Rey, also included other presentations on pavement preservation, specifications and quality assurance. 

Open House Showcases Overlay on Vital KY Parkway

Almost 40 people participated in an open house event yesterday in Elizabethtown, KY.  The event was of special significance because of its focus on a 6-in. thick unbonded concrete overlay on the Bluegrass Parkway (from mile marker 0 to 6). 

This Kentucky Transportation Cabinet project is being constructed on a vital section of highway connects with Interstate 65 to the west and U.S. Route 60 to the east.  

The event started with a briefing and a luncheon at the City’s Pritchard Community Center. Greg Smith, Director of Paving Technology for the Kentucky Concrete Pavement Association, covered some recent concrete overlay projects in Kentucky and Indiana, national perspectives and statistics, and an overview of the project. He also presented many design tools and other resources offered by ACPA (including www.pavementDesigner.org), along with resources offered by the CP Tech Center. 

Tony Korba, Operations Manager at E&B Paving, an ACPA member, provided details about the construction of the Blue Grass overlay project, covering details about smoothness, joints, paving challenges, and fibers. 

Following the briefing, participants then loaded a bus and headed to the project site, where they had the opportunity to see the concrete overlay and discuss specifics about project on the WB lane of the Bluegrass Parkway, one of seven highways that are part of the Commonwealth’s parkway system.

Bill Davenport from ACPA was on hand to chronicle the event, which will be produced as a video report soon. The project also will be covered in an upcoming issue of CONCRETE PAVEMENT PROGRESS magazine. 

Mid-Atlantic Chapter Offers Training & Tech Transfer

In this week’s continuing coverage of “Gold Standard” Chapter events, we’re pleased to highlight two of the tech transfer events in which the Mid-Atlantic Chapter has been involved recently.  Chapter President Ray Seipp covers a multi-state region and has been working proactively to provide training and tech transfer opportunities to customers.

In late March, Ray participated in the Southeast Pavement Preservation Workshop in Charleston, WV.  The event drew an estimated 150 people reepresenting industry, agencies, and academia.  The workshop focused on preservation’s role in sustainability and included two days of updates, sustainability-focused presentations, roundtable discussions, and other meetings.  

The prior week, Ray joined with Gordon Smith and Jerod Gross of the CP Tech Center to present back-to-back workshops to key employees of the West Virginia DOT’s Division of Highways employees in Princeton, WV.  More than 50 employees attended the Concrete Overlay Workshop on March 20 and the Inspector’s Workshop on March 21.

Highlights of the CP Road Map

The latest news about the long-term plan for the Concrete Pavement Research and Technology, also called the CP Road Map, includes some excellent updates.  Here are two that caught our attention:

  • The publication of a research report called, “Reliable Early Opening Strength for Concrete Pavements and Patch Work,” which presents results of study by the Louisiana Transportation Research Center.  The research evaluated jointed plain concrete pavement performance in relation to dowel bar alignment using the new MIT-SCAN2-BT technology.
  • The CP Tech Center has published a comprehensive report called “Technology Transfer of Concrete Pavement Technologies,” which summarizes the accomplishments asssociated with the cooperative agreement between the center and the FHWA over the past five years. The goal of this project was to help bring the latest concrete pavement innovations, knowledge, and technologies to state transportation agencies in support of the Accelerated Implementation and Deployment of Pavement Technologies (AID-PT)* program goals.  The cooperative agreement was a direct result of ACPA’s ongoing advocacy efforts, which not only led to the vision and direction of AID-PT, as well as benefits to the concrete pavement community.

These and other reports may be found in the current issue of CP Road Map E-News, produced by Dale Harrington and Sabrina Shields-Cook. 

______________________
* AID-PT was the result of a legislative provision championed by ACPA and included in both the Moving Ahead for Progress in the 21st Century Act (MAP 21) and more recently, the Fixing America’s Surface Transportation Act (FAST Act), signed into law in December 2015. AID-PT created both a mechanism and funding for the delivery of pavement technology for both the concrete- and asphalt-pavement industries. Since its inception, the program has resulted in benefits to the concrete pavement community, including other contracts and cooperative agreements with CP Tech Center, an ACPA Technology Partner.
