Webinar to Focus on Performance Engineered Mixtures

The CP Tech Center will be holding a webinar on Performance Engineered Mixtures (PEM) for Concrete Pavements on June 27, from 10 a.m. to 11 a.m. (CDT). 

The PEM program is designed for agencies to specify and contractors to deliver quality materials for durable concrete pavements every time.

Join presenters Peter Taylor (CP Tech Center) and Kevin McMullen (Wisconsin Concrete Pavement Association) as they dsescribe how can shape the present and future of concrete pavement construction & rehabilitation.

CP Tech Center Seeks Program Manager

The Department of Civil, Construction & Environmental Engineering (CCEE) and the Institute for Transportation (InTrans) at Iowa State University is currently accepting applications for a Program Manager.

The successful applicant will service as a lab supervisor and manager for the PCC Lab housed in Town Engineering and manage field activities undertaken under the guidance of the PCC lab. This position will supervise all personnel working within the laboratory including faculty, staff, graduate and undergraduate students, visiting scholars, and post-doctoral researchers.  Click here see additional duties, academic and experential requirements, and other details.

 

CP Tech Center Announces Overlay Performance Report

The CP Tech Center announced a new study on pavement overlay performance. “Automated Plate Load Testing on Concrete Pavement Overlays with Geotextile and Asphalt Interlayers: Poweshiek County Road V-18,” offers an assessment of the performance of unbonded concrete overlay sections applied in 2008–2009.

The  authors (David White and Peter Taylor) compare overlays constructed in 2008 to 2009 using an asphalt interlayer or a non-woven geotextile fabric interlayer. 

One of the findings was the concrete overlays placed over the geotextile exhibited lower permanent deformation than those placed over asphalt interlayer.

Video Honors Gordon Smith

In case you missed it, we thought you might like to see this very well produced video, which honors Gordon Smith, formerly of the ICPA, and currently with the CP Tech Center.   The video was unveiled at he ICPA’s 54th Annual Workshop last month, but we think it’s worth a look (or a second look).   Click here to see the video, which can also be found on ACPA’s YouTube video channel.

Calling All Contractors: Please Respond to RCA Survey

ACPA is urging contractor members to respond to the Annual Recycled Concrete Aggregate (RCA) Survey for 2017 projects.  ACPA sent the survey early Monday morning, and is requesting responses by Friday, April 13.  

The FHWA has identified concrete pavement recycling as an important area of interest, and has urged industry to gather strategic information. Currently, there is no known source of information that accurately captures the degree with which concrete pavements are recycled or re-used, nor do we know for certain what barriers exist that may hamper the degree of concrete pavement recycling or RCA usage.  This survey, now conducted annually by the American Concrete Pavement Association (ACPA) in partnership with FHWA and National Concrete Pavement Technology Center (CPTech Center), intends to address questions about RCA.

If you’re an ACPA contractor member and did not receive the survey, please contact Bill Davenport (bdavenport@acpa.org | 847.423.8703).   Want to know more about the survey and why it’s important?  Please contact Leif Wathne (lwathne@acpa.org | 202.638.2272)
