NRMCA Attends, Reports on National Concrete Consortium Meeting
About 180 attendees from state agencies and industry convened at the Spring National Concrete Consortium (NCC) meeting in Coeur d’Alene, ID, this past week. The NCC is a national forum for concrete pavement research and technology transfer initiatives and is supported through a FHWA Pooled Fund TPF-5(159). There are 33 participating state highway agencies.
The primary theme of this meeting was on performance-engineered mixtures for concrete pavements with updates from the National Concrete Pavement Technology Center, the FHWA mobile trailer, FHWA and its Turner Fairbanks Research Center. Implementation initiatives by Michigan and Idaho were reported. Jason Weiss of Oregon State University discussed the evolution of new test methods for transport properties of concrete and resistance to freezing and thawing. Tyler Ley of Oklahoma State University presented research on a new method to measure water-cement ratio of concrete and on factors to consider for formwork removal. Other presentations included practices for latex modified concrete overlays in North Carolina and Missouri; reclaiming fly ash from legacy ponds by a burn-out process; alternative cementitious materials; fiber-reinforced polymer (FRP) reinforcement and various other state reports. The group ended the meeting with a technical tour of concrete pavement project at Lookout Pass-Montana state line.
