FHWA Group Focuses on Sustainability Resources

The 18th meeting of the Sustainable Pavements Technical Working Group (SPTWG) gave stakeholders the opportunity stakeholders to provide technical input on sustainability and environmental aspects of pavements and pavement materials. The meeting, which began with opening remarks by Heather Dyllla, FHWA Sustainability Program Manager, also created a forum to share information and discuss resources.

Held in Detroit last week, the two-day meeting covered a wide variety of topics, including streets and urban sustainability, innovations by the Michigan DOT, and product category rules (PCRs) and environmental product declarations (EPDs). The meeting also addressed life cycle analysis data issues and included a demonstration of the FHWA’s LCA tool.

Participants also heard a presentation on pavement vehicle interaction (PVI) by Karim Chatti, Michigan State University; Imad Al-Qadi, University of Illinois; and Jeremy Gregory, of the Massachusetts Institute of Technology (and CS Hub). A PVI panel discussion followed and addressed timely questions about PVI, including gaps in modeling, as well as implementation steps for using PVI models in the short term. Technical updates presented by the FHWA included an update on the FHWA PVI study and sustainable pavement studies. 

Facilitating and participating in the discussions were Kurt Smith and Prashant Ram of ApTech, an ACPA member. Leif Wathne participated in the meeting, representing ACPA and the concrete pavement industry’s perspectives. 

Join the Discussion on Concrete Roundabouts

The FHWA has declared this week as National Roundabouts Week.  To promote the safety, environmental and performance benefits of concrete roundabouts, ACPA National and affiliated Chapters are posting photos, videos, and infographics all week (Sept. 16 through 20). 

As part of our ongoing development of marketing and promotional strategies and tactics, ACPA developed a series of infographics earlier this summer to address some of the benefits of concrete pavement roundabouts. 

We encourage all members, affiliates, and technology partners to join us and others in discussing roundabouts on Facebook, Instagram, LinkedIn, Twitter and other social media and communications channels.  Be sure to tag your posts with #RoundaboutsWeek.

Are You Using MIT’s Carbin App?

MIT’s CARBIN app* allows drivers to measure road quality and sustainability factors in their area.  The app is available through either the Apple Store for iPhones and the Google Play Store for Android phones.  

Recent improvements in the app have enhanced this automatized system, which can be easily used to extract information on the quality of roads and their environmental impact at the city, state, or country scale.  In related news, MIT is reminding users using to place their phones in a stable position before they start driving. 

After using the app, be sure to check the results from your data inputs, as well as others who are contributing to this project by visiting: www.fixmyroad.us.  

The MIT Concrete Sustainability Hub (CSHub) also has a videotaped presentation on the “Fix My Road” initiative, including details about the “Carbin” smartphone app, a crowd-sourced tool that is building an ever-increasing amount of information about the condition of the world’s highways and roads. Click here to view.

Learn More About MIT’s Carbin App

The MIT Concrete Sustainability Hub (CSHub) will present a one-hour webinar to provide an update on the “Carbin” smartphone app, a crowd-sourced tool that is building an ever-increasing amount of information about the condition of the world’s highways and roads.  Scheduled for  Thursday, September 26, at 10 a.m. (CDT) | 11 a.m.  (EDT),  the webinar is called, “The Carbin App: Cutting CO2 Emissions and Monitoring the Performance of our Roads.”

The webinar will be hosted by CSHub research assistant Jake Roxon. The webinar will include an update on the Carbin app, including recent improvements that have created an automatized system which can be easily used to extract information on the quality of roads and their environmental impact at the city, state, or country scale.  The webinar is free of charge, but registration is required.  Click here for details and to register for the webinar.

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.
