National Concrete Consortium Spotlights Concrete Patching Research

The National Concrete Consortium (NC2), in its latest NC2 E-News, focuses on concrete patching with its coverage of the Concrete Infrastructure Research Database of in-progress and recently completed research.

Maintained by the CP Tech Center, the database allows easy search of curated research related to concrete pavements and bridge decks across the US from the previous 5 years. Originally developed under the former CP Road Map, research included in the database is identified from the Transportation Research Board (TRB) list of Research in Progress (RiP), newsletters from across the concrete industry, and agency websites.

The current NC2 e-newsletter shows an example of available research based on the phrase “concrete pavement patching.” (See inset illustration.)

The database also includes recent research on a wide range of topics and is useful for agencies, engineers, and others with an interest in current pavement research.

ACPA Participates in National Concrete Consortium Meeting

The National Concrete Consortium (NC2) held its Fall meeting last week. Eric Ferrebee and Larry Scofield participated in the meeting, which consisted of a series of 3-hour webinars held last Tuesday through Thursday.

The NC2 Meetings are hosted by the CP Tech Center as a venue for federal and state agencies, academia, and industry to discuss concrete pavement research and technology transfer initiatives.

Each day’s three-hour webinar featured two main themes related to concrete research and technology. Tuesday’s topics included alkali-silica reactivity (ASR) and lightweight cellular concrete. Each topic featured a variety of presenters including representatives from FHWA and PCA.

The program for Wednesday included State’s Experiences with performance engineered mixture (PEM) testing and dowel and tie bar performance, interactions, and experiences. Wednesday’s presenters included Kevin McMullen of the Wisconsin Concrete Pavement Association. He presented an update on Wisconsin’s PEM implementation.

On Thursday, presentations included an update on the National Transportation Product Evaluation Program (NTPEP) and other project updates, including a presentation by Dr. Tyler Ley of Oklahoma State University.  His presentation explained what happens to the concrete air void system as the material is pumped.

The recorded webinars, along with the PDF copies of the presentations, can be accessed on the CP Tech Center’s website at: https://intrans.iastate.edu/events/fall-2020-national-concrete-consortium/. The next NC2 Is scheduled for April 13 – 15 in Nashville, Tennessee.

National Concrete Consortium Postpones Spring Meeting

The Spring 2020 National Concrete Consortium, originally scheduled for this month, has been postponed. This followed similar actions associated with the COVID-19 pandemic, accoding to the CP Tech Center, which manages registrations.  

Those who have made plans to participate in the meeting are asked to cancel reservations with the Embassy Suites Nashville Airport by calling 1.800.Embassy or 1.800.362.2779. The CP Tech Center is checking calendars and working with the Nashville hotel in hopes of rescheduling the meeting. In the interim, registration fees will be refunded.

Deadlines Approach for National Concrete Consortium Meeting

The National Concrete Consortium (NCC) hotel room block for the spring 2020 meeting is March 9th, according to the CP Tech Center, which manages registration for NCC. If you need a room at the Embassy Suites by Hilton-Nashville Airport, please click here or call 615.522.5444 and request the NCC block rate ($179).

A welcome reception kicks off the meeting from 5:30 to 7:00 p.m. (CDT) on Monday, March 30. The meeting follows on Tuesday, March 31, through Thursday, April 2. Anyone interested in the meeting should register no later than Friday, March 20. 

See Highlights from CP Road Map and NCC

The latest issue of the National Concrete Consortium (NCC) News* provides an update on the CP Road Map plan jointly developed and implemented by concrete pavement stakeholders, including ACPA and the CP Tech Center. Here are summaries of three reports that caught our eye:

Investigation of the Iowa DOT bridge deck epoxy injection process – This report summarizes how the injection of epoxy resin into the cracks and voids on concrete overlays has been used across Iowa.  The technique has had positive results in preserving concrete overlays, which have been used on bridge decks in Iowa since the 1970s.  

Environmental Impacts and Design on Performance – This report details a study of the effects of environmental factors and pavement design on pavement performance in the absence of heavy loads. Results showed an average of 36% and 24% of total damage was related to environmental factors for flexible and rigid pavements, respectively, at 15 years.

A Cost-Effective Ultra-High Performance Concrete (UHPC) – This report presents the development of UHPC using locally available materials in Colorado.  Locally sourced materials are said to reduce construction costs when compared to commercially produced products. The report examines implications of various constituent types with an emphasis on silica compounds, steel and polypropylene fibers.
