Article about West Des Moines project in Roads and Bridges

The September 2016 issue of Roads and Bridges includes an article (see page 45) about a West Des Moines paving project that used a modified mixture design for long-life durable concrete pavements and joints. This project relied on research by the CP Tech Center and its partners. In particular, the mix had relatively high Class C fly ash content and relatively low water-to-cementitious-materials ratio. See the center's related research report.

Showcase on pavement smoothness a success

Fifty-eight people representing nine state DOTs, FHWA, contractors, and industry attended the Aug. 9, 2016, national showcase of real-time smoothness (RTS) technologies for concrete pavements in Salt Lake City. Hosted by the Utah DOT and organized by the CP Tech Center, the event provided participants with information about RTS technologies and an opportunity to observe such technologies in action. Following a morning workshop, the attendees were bussed to a project site where RTS equipment was demonstrated.

The showcase was part of the FHWA-sponsored SHRP2 Renewal project on real-time smoothness measurements, which also includes loaning RTS equipment to state DOTs and contractors.

Highlights from fall 2016 NC2 meeting

At the joint 11th International Conference on Concrete Pavements/fall NC2 meeting in San Antonio (Aug. 29–Sep. 1, 2016), NC2 state representatives moderated 14 sessions, made 20 poster presentations, provided 10 speakers and two papers, and attended their choice of 14 podium sessions and 10 workshops.

The NC2 states also met on Monday afternoon to discuss sponsored activities through the Technology Transfer Concrete Consortium pooled fund (e.g., upcoming training, priority technical topics) and share information about state research activities. See meeting highlights.

Note: To facilitate the sharing of state research info among NC2 states, links to state DOT research pages will soon be provided on the CP Tech Center/NC2 website.

Study completed re pavement monitoring via embedded sensors

See volume I (field demo) and volume II (development of sensor system) of the project report: Development of a Wireless MEMS Multifunction Sensor System and Field Demonstration of Embedded Sensors for Monitoring Concrete Pavements, or see the 4-page tech transfer summary.

Coming: Web-based training on concrete pavement preservation

The FHWA has awarded the CP Tech Center a project to develop English and Spanish versions of four interactive, web-based training modules on concrete pavement preservation. Focusing on the needs of paving contractors and technicians, the modules will cover the following topics: full-depth patching, partial-depth patching, dowel bar retrofitting, cross-stitching, and diamond grinding.
