Time to sign up for Iowa Concrete Pavement (SPS-2) Tech Day

Join us in Des Moines on May 30 for timely discussions of concrete pavement preservation treatments and learn how Iowa's SPS-2 will be used for further concrete preservation research. Speakers from government and industry will report on findings from national surveys on expected service lives of concrete preservation practices. Results of the Phase 2 project for the SPS-2 Concrete Preservation Pooled Fund project will be shared. The CP Tech Center is one of the day's sponsors, along with the Iowa DOT, FHWA, and four concrete industry agencies. There is no cost to attend the event, but registration is required.

Taylor, Smith headline recent Manitoba concrete pavement workshop

Two of the CP Tech leadership team members journeyed to Winnipeg, Manitoba, Canada to present a concrete preservation-focused program at an April workshop. Gordon Smith, associate director, spoke on the concrete pavement experience in Iowa, steel placement, and joint layout and post-placement activities. Peter Taylor, director, talked about joint performance, limestone aggregates in Iowa, and concrete mix designs.

The early workshop sessions discussed pavement evaluation, repairs, retrofits, and rehabilitation, while the later offerings covered the more technical aspects of concrete production and performance. The workshop was a collaborative effort of Manitoba Infrastructure, City of Winnipeg, the Transportation Committee of Manitoba, Concrete Manitoba, and the Cement Association of Canada.

Tritsch travels take him from Delaware to Texas

Like his colleagues, CP Tech Center associate director Steve Tritsch has been on the road, giving presentations of interest. In April, he participated in the Long Life, Low Maintenance Concrete Conference in Austin, Texas. There he spoke on "Deicing Salts - Mitigating the Effects". March saw him attending two concrete-related events. He spoke on "Performance of Overlays in Iowa" at the meeting of the Oklahoma/Arkansas Chapter of the American Concrete Pavement Association. At the West Virginia Department of Highways Pavement Preservation Conference, he presented on full-depth reclamation, dowel bar retrofit, and joint resealing. Earlier in 2018 he shared research findings on "Alkali-Carbonate Reaction - An Ongoing Study" as part of the Mid-Atlantic Quality Assurance Workshop in Dover, Delaware.
