NC² States’ Q&A Listserv
The National Concrete Consortium (NC²) States’ Q&A Listserv is used by TTCC pooled fund member states to poll other member states about concrete paving and bridge deck issues.
Polling states then share with NC² question-and-answer spreadsheets/pdfs, which are downloadable by clicking the appropriate topic link in the table below.
