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.
