Webinar to Cover Overlay Research and Performance

A Transportation Research Board webinar will cover “Concrete Overlay Performance & Research Innovations.” Those interested are encouraged to register as soon as possible.  The webinar will be held Thursday, Sept. 5, from noon to 2:00 p.m. (CDT) |1:00 to 3:00 p.m. (EDT).

The two-hour webinar will describe highway agencies’ experiences with concrete overlays, along with experiences with recent innovations, including interlayers and fiber reinforcement.  Presenters will discuss case studies of concrete overlays and illustrate design considerations of this technique. 

Moderated by Kurt Smith, Applied Pavement Technology, Inc.,* the webinar will be presented by John Donahoe, Missouri Department of Transportation, Dan DeGraaf, Michigan Concrete Association; Julie Vandenbossche, University of Pittsburgh,* and Jeff Roesler, University of Illinois and President-ISCP.* A certificate for 2.0 PDHs will be provided to professional engineers who register and attend the webinar individually.  Click here for more information, including registration details.

Arkansas Workshop Focuses on Innovation

The 2019 Arkansas Concrete Pavement Conference last week drew an estimated 175 professionals to Little Rock to learn about and discuss the latest innovations in concrete pavement design, construction and maintenance. 

Alan Meadors kicked off the formal program, which included opening remarks by Scott Bennett, Arkansas DOT Director and FHWA perspectives presented by. Angel Correa, and an overview of ACPA activities and inter-industry competition by Leif Wathne, ACPA.  Technical presentations included:

  • Achieving pavement smoothness by Luke Stovall of Weaver-Bailey Contractors;* 
  • Preserving concrete pavements: making the right choice by John Roberts of IGGA;
  • Concrete research activities by Dr. Micah Hale, University of Arkansas;
  • Transitioning from PI to IRI for compliance by John Donahue, of the Missouri DOT;
  • Precast panels for highway construction by Sam Tyson of FHWA; 
  • Performance and use of sealants on concrete pavements by Dr. Cameron Murray, University of Arkansas; and 
  • A National Concrete Pavement Technology Center Update by Dr. Peter Taylor of the CP Tech Center.

The conference also included a presentation of a $100,000 check from the Chapter to the University of Arkansas in support of concrete initiatives.  The contribution is part of a five-year commitment by the Oklahoma/Arkansas Chapter.  Another highlight of the annual conference were the refreshment breaks, where participants had the opportunity to visit with and see exhibits by sponsors.

Learn More About MIT’s Carbin App

The MIT Concrete Sustainability Hub (CSHub) will present a one-hour webinar to provide an update on the “Carbin” smartphone app, a crowd-sourced tool that is building an ever-increasing amount of information about the condition of the world’s highways and roads.  Scheduled for  Thursday, September 26, at 10 a.m. (CDT) | 11 a.m.  (EDT),  the webinar is called, “The Carbin App: Cutting CO2 Emissions and Monitoring the Performance of our Roads.”

The webinar will be hosted by CSHub research assistant Jake Roxon. The webinar will include an update on the Carbin app, including recent improvements that have created an automatized system which can be easily used to extract information on the quality of roads and their environmental impact at the city, state, or country scale.  The webinar is free of charge, but registration is required.  Click here for details and to register for the webinar.

Did you know you can contribute to this project?  To start, download MIT’s CARBIN app,* which is available through either the Apple Store for iPhones and the Google Play Store for Android phones.  See the results from your data inputs, as well as others who are contributing to this project by visiting:  

Illustration shows quality of US roads, one of three data sets found on, the MIT CSHub’s website that shows the condition of highways and roads.  In addition to overall quality, the website also shows environmental impact and road roughness.

* Please note: MIT will not collect your personnel information; the app “sees” each phone only as an anonymous, randomly assigned number that cannot be linked to any personal data. 


ACPA Previews NC2

NC2, the semi-annual technical and peer-exchange forum for concrete stakeholders, meets September 10 through 12, in Kalispell, MT.  The fall meeting will include updates and state reports, including reports by the FHWA and the CP Tech Center, followed by a Q&A session and open discussion. Themed discussions and presentations on the will focus on  early opening technologies; precast materials; topical treatments and repair techniques for concrete; dowel bars in concrete pavements; innovation updates;  and bridge deck curing. 

Eric Ferrebee of ACPA will present on dowel bar placement methods, issues and verification.  ACPA partners CP Tech Center and IGGA will be presenting on several topics, including: a performance engineered mixtures update by Gordon Smith, CP Tech Center, and load transfer device optimization by Larry Scofield of IGGA.  Also of interest to ACPA is the presentation on using EMI in field testing by Dr. Luna Lu of Purdue University. (See the related story, Purdue Team Using Piezoelectric Tech for Concrete Maturity Testing.) 

ACPA members also are on the program discussions about implementing maturity systems by Sabrina Garber, of The Transtec Group*; performance-based specification for dowel bars by Dr. Mark Snyder, Pavement Engineering and Research Consultants*; and IRI and real-time smoothness by Gary Fick and Dave Merritt of The Transtec Group.*

A technical presentation about the Hungry Horse Dam and an optional tour of the dam, along with a Technology Transfer Concrete Consortium (TTCC) meeting for state agencies are also on the agenda. 

NC2 meetings typically draw more than 150 attendees from the Federal Highway Administration, 35 member DOTs, the Illinois State Toll Highway Authority, industry and academia.  The meetings are excellent forums for participants to discuss common issues and experiences related to concrete pavements and structures.

ACPA Announces Paving Award Recipients

ACPA announced today the recipients of the 30th Annual “Excellence in Concrete Pavement” awards. Click here to see the overall award recipients. In keeping with tradition, the announcement of the “Gold” and “Silver” awards remains a secret until the award presentation ceremony during the annual meeting.

In announcing the awards, the association recognizes 27 award-winning projects, along with the hard work, outstanding quality, and creative approaches to problem solving demonstrated by contractors, agencies and engineers. In all, ACPA recognizes 23 unique contractors, whose exceptional projects span 15 affiliated chapter/state association areas. Forty-one professionals served as judges of the award submittals, reviewing nomination forms, project details, and photos depicting the projects.

The annual awards are one of the highlights of our annual meeting each year, and this year will be no exception. In early September, award winners will receive an invitation letter to attend the 30th awards banquet. The banquet will be held during the ACPA 56th Annual Meeting. The ceremony will take place on Thursday, December 5th at the New Orleans Marriott.
