Federal Highway Administration Recycling Technology Program Could Green

Federal Highway Administration - Recycling Technology Program Could Green Roads lead to Green Buildings?

Where we are going today n n n n FHWA Recycling Policy RMRC Our Recycling Targets Partners Targets and who are our Partners GHP Green Highway Technology So you have an ideal – how to work with state DOT!? !? !?

Why We Are Here Today? n We are stewards of our Environment but: n n n We have lots of High Quality & Low Cost Aggregates for future needs Plenty of landfill space to use & low tip fees Public & Government have no recycling or environmental concern to address n n URBAN Quarry FACT!! n n Plenty of money, recycling is bad word. Greenhouse gases is not an issue. Many of our BEST materials are already in use Need to work to change “waste” to be a desired resource

WHY FHWA Promotes Recycling? FHWA’s Mission/Goal statements n Economical Savings Potentials n Performance Enhancements n Saving “Non-Renewable” Resources n Cooperative Partnerships with Industry – helps their bottom line n Just “Darn Good” Practice n

FHWA Recycled Materials Policy FHWA recognize the need to increase our highway industry's overall use of recycled materials n Forge partnerships among government, industry, and academia n Continue to strengthen the relationship between FHWA, US EPA, and State DOT/DEQ n n www. fhwa. dot. gov/legsregs/directives/policy/ recmatmemo. htm

Key Points 0 f FHWA Recycling Policy n n n Recycled/Re-Use materials are viable resources Recycled materials should get first consideration in overall materials selection. Recycling does offer engineering, economic and environmental benefits. Material should not adversely impact the environment and should perform as intended Restrictions prohibiting recycled material that are without technical basis should be removed.

We Need to Recycle Need to reconstruct much of the infrastructure built in the 50’s and 60’s n Virgin materials are being depleted n The cost of virgin materials are increasing n Need to maximize the material resource (non-renewable) n Advanced in technology to better control process n

What are Non-Renewable Resources?

BIG!! Demand for Materials n n n 160, 000 mile National Highway System 4 million miles of public roads & 590, 000 bridges Produce over 600 million tons of HMA annually & 85+ million SY of concrete for paving annually $70 billion capital outlay to maintain pavements Demand for aggregates considerable requiring an estimated 700+ million tons to meet annual demand (15%-25% of annual production)

Recycled Materials Resource Center n University of New Hampshire n University of Wisconsin – Madison n University of Washington – unofficially n www. recycledmaterials. org

Underlying Goals of RMRC • Define and break down barriers to use of recycled materials and industrial byproducts in transportation applications. • Responsive to the needs of stakeholders: FHWA & EPA, State and Local DOTs, & Byproduct generators. (the industry) • Practical research coupled with outreach activities oriented towards practical application of recycled materials and industrial byproducts.

FHWA Targets In-house Recycled Concrete Aggregate Reclaimed Asphalt Pavement

FHWA’s Our Do It 1 st Targets n Clean up our own “Home” n n Expert Task Group for RAP Technology n n n RAP (Reclaimed Asphalt Pavement) RCA (Recycled Concrete Aggregate) Steel – done! NAPA and AASHTO In-place Asphalt Technology - ARRA RCA n n FHWA/USEPA/RMRC - National Review on practices New TA - Use of Recycled Concrete Pavement as Aggregate in Hydraulic-Cement Concrete Pavement

RAP – Reclaimed Asphalt Pavement n Millings from road reconstruction n Process of milling – renovated highway industry rehabilitation program Commercial removal. C&D n 100+ million tons from highway work n ~80% reused in highway system n FHWA and HMA Industry wants to increase % recycled n n Why? -Economics & Environment

Allowances and Use of RAP in Flexible Pavement Layers Surface Allowed by specs 18 % Average Used 12 % Potential 26 % Binder Allowed by specs 23 % Average Used 18 % Potential 33 % Base Allowed by specs 27 % Average Used 21 % Potential 36 % Opportunity to Increase the Use of RAP 17% Increase to meet specifications 44% Possible Increase in RAP Use

Average Use of RAP in the US Average Amount of RAP Specified in Surface Mixes Jones, Cecil. Results of Survey on State RAP Usage, Presented at RAP Expert Task Group Meeting, 2007.

Recycled Concrete Aggregate n Iowa State University n n n n Concrete Pavement Technology Program (CPTP) Industry Partners involved TA on use of RCA in PCC pavement Research on properties – blended GHP focus. FHWA/USEPA/RMRC National Review – State of Practice on Use of RCA More items in future work plans Needs higher emphasis for use at higher value

Describing the Mid-Atlantic Green Highways Partnership n n Broad Based Partnership Leveraging of Knowledge, Experience, & Resources n Sharing, capturing, researching, depository n Doing Business Differently n Leaving Things “Better Than Before”

GHP Mid-Atlantic Team Structure Ad Hoc Committee Watershed Based Stormwater Management Team Promote the watershed -driven address of stormwater impacts through the use of practices that eliminate flow and loads by 90100% and allow for innovative approaches to stormwater and watershed trading. Recycle & Reuse of Industrial Byproducts Conservation & Ecosystem Protection Team Establish a Regional Ecosystem Framework Develop Conservation Ecosystem approaches focused for Transportation

So you have an idea? !! n State DOT n New product committee n Materials Engineers – info on getting in the loop n Ask what it takes to be on approved material list. n Material lab testing requirements – you pay! n Small project demonstration – you provide n Case studies from other state DOTs help.

Networking FHWA has office in EVERY State n Might help to have copy of our policy in hand. n They can network you with the State DOT n University Civil Engineer Dept n University Transportation Centers n n http: //utc. dot. gov/
