CP Tech Center Releases RCA Report

The CP Tech Center has released a report summarizing key findings of a research project aimed at gaining a better understanding of where and how extensively concrete pavement recycling and recycled concrete aggregates (RCAs) are being used in the United States.  

“Recycled Concrete Aggregate Usage in the US” is a 38-page report that describes the two-phase benchmarking research project, origins of concrete pavement recycling and factors driving the need to recycle and reuse RCAs. 

The four-color publication begins with an introduction and background information, details about the opportunities for sustainable material practices in concrete pavement construction and rehabilitation, and details from the survey on RCA use in roadway applications. The report also includes conclusions and recommendations, as well as details about ACPA’s plans for tracking data and working to train members (and support the FHWA and state DOTs) in specification and policy development focusing on the beneficial use of existing concrete pavements. 

Although the survey was not funded by the Federal Highway Administration (FHWA), the results have helped guide the work on technology transfer under one of their cooperative agreements. The results have been made fully available to support the FHWA’s goals of supporting more sustainable pavement technical solutions.  ACPA member contractors were among those who assisted the research by participating in surveys presented by ACPA.

Florida Design-Build Team Takes Sustainability Award

ACPA presented the 2018 Sustainability Practices Award to the Florida DOT and Archer Western Construction.

The two organizations were recognized for their innovative design-build team which proposed, engineered, and built a 16-ft wide  full-depth concrete shoulder to serve as an emergency lane along State Route 98 in Jacksonville.

The decision to provide the emergency lane reflects forward-thinking context sensitivity, which is rare and an inherently important part of sustainable construction. 

This is a positive example of including the societal benefit of avoiding future construction costs and eliminating future lane closures.

An official of Archer Western Construction accepted the award on behalf of the design-build team. 

FHWA Seeks Long-Life and Sustainable Pavement Projects Ideas

The Federal Highway Administration is looking for good examples of long-life pavement projects and projects that incorporate sustainable practices for case study consideration.

Concrete Sustainability Hub to Present LCCA Webinar

The MIT Concrete Sustainability Hub (CS Hub) will host a free public webinar, “Pavement Life Cycle Cost Analysis (LCCA): Price Projection Modeling,” on March 30 at 11 a.m. (EST).

The webinar is designed to provide engineers, designers, and decision makers with a better understanding of the economic impacts of infrastructure decisions over time, as well as to identify opportunities to reduce impacts.

This webinar will present the CSHub’s pavement-related LCCA research, including a study conducted in collaboration with the Colorado Department of Transportation which showed material-specific price projections are more accurate than the conventional assumption that pavement prices follow the average rate of economic inflation.

About the CS Hub
The CSHub at the Massachusetts Institute of Technology (MIT) was established in 2009 with funding from the Ready Mixed Concrete (RMC) Research & Education Foundation and the Portland Cement Association (PCA). The mission of the CSHub is to develop breakthroughs that will achieve sustainable and durable homes, buildings, and infrastructure.

Concrete Sustainability Hub to Host Webinar

The MIT Concrete Sustainability Hub (CS Hub) will host a public webinar, “An Overview of CSHub Pavements Research” on Thursday, March 2, begining at 11 a.m.  (CST). The webinar will be presented by Jeremy Gregory, Ph.D., Executive Director of the CSHub.

To register for the webinar, please follow this link, or alternatively, paste the link to your web browser: http://tinyurl.com/cshubwebinarMarch2.

The webinar will provide an overview of pavements research at the CS Hub. Pavements-related research by the MIT CSHub focuses on improving pavement design, maintenance, and network management, which can lead to increased fuel efficiency, lower maintenance costs, and better life cycle planning. Topics discussed will include life cycle assessment; life cycle cost analysis; pavement vehicle interaction; and pavement albedo.

This webinar is free of charge and is open to the public.
