Full-depth reclamation with cement publication is now available

Front cover of the Guide to the Prevention and Restoration of Early Joint Deterioration in Concrete Pavements

A new guide about a sustainable engineering technology in pavement rehabilitation has been published by the National Concrete Pavement Technology Center.

The "Guide to Full-Depth Reclamation (FDR) with Cement" introduces the FDR with cement process and examines issues related to project selection, design, construction, and testing and quality control. The Portland Cement Association sponsored the 90-page guide.

Sustainable engineering technologies in pavement rehabilitation, such as FDR, could be the answer for agencies in their quest to provide taxpayers with high-quality infrastructure while being good stewards of public funds, according to the guide.

To purchase a printed copy of the guide, contact Wayne Adaska at PCA.

Best Practices workshops continue

Concrete Pavement Best Practices workshops continue this spring. Sponsored by the Federal Highway Administration and the CP Tech Center, the workshops provide sessions on gradations, supplementary cementitious materials, materials-related distress, dowel anchoring, and quality assurance.

The next workshop is May 18 in Salt Lake City, and two additional workshops are planned for June. Earlier workshops were April 20 in Kansas City, Kansas, and May 9 in Gainesville, Florida.

Webinars from previous sessions are available for the topics covered by the workshops.

NCC spring meetings

The National Concrete Consortium (NC2) spring meeting, hosted by the Utah DOT in Salt Lake City, had 172 attendees from the FHWA, 30 DOTs, the Illinois Tollway, academia, and industry.

Meeting highlights:

  • Update of the K96 High Performance Concrete Pavement built in 1997 with 12 test sections each approximately 3,000 feet long.
  • FHWA updates on the Sustainable Pavement Program, the Mobile Concrete Lab, HIPERPAVE, and PEM.
  • State, academia, and industry reports.
  • Revising AASHTO M254 to include alternate type dowel bars.
  • Election of new Executive Board members.

The fall meeting is September 19-21, 2017, in Minneapolis.

Spring and summer webinars

Registration is open for two remaining new 90-minute webinars offered in spring and summer 2017. Register for the dates and times that work best for you.

Concrete pavement recycling (developed through an agreement with FHWA):

Environmental Considerations in Concrete Pavement Recycling

May 18: 10:00 a.m. Central
As agencies are looking for opportunities to become more sustainable in their stewardship of public infrastructure, many are looking at applications for recycling existing concrete pavements on projects. This webinar gives practitioners an overview of the issues, approaches, and environmental benefits of RCA as a valuable engineered material. Topics include water quality, air quality, noise, waste generation, and minimizing/mitigating these issues.
Instructor: Tara Cavalline, UNC-Charlotte

Case Studies in Concrete Pavement Recycling

May 24, June 21, or July 12: 10:00 a.m. Central
RCA has been used successfully in various applications on hundreds of paving projects built throughout the United States since the 1940s. This vast national experience offers many lessons. This webinar provides a working knowledge of opportunities for using RCA in pavement applications by reviewing the design, construction, and performance of concrete pavement recycling projects that have helped to shape current recommended RCA practices. Topics include structural design issues when using RCA in any layer, recycling D-cracked or ASR-damaged concrete, beneficial mix design modifications when using RCA, advancements in construction equipment, and documentation of economic benefits.
