Sustainable Design and Construction of Airfield Pavements! FAA Eastern Region 33rd Annual Airport Conference March 3, 2010 – Hershey, PA
“Triple Bottom Line” John Elkington Proposed the “Triple Bottom Line” or the principle of Sustainability.
Green vs. Sustainability “Green” – Focuses solely on Environmental Stewardship or one component of the “Triple Bottom Line”. “Sustainable” – Includes the ‘Green’ aspect of a project and also integrates the other two components of Economic Growth and Social Responsibility.
Environmental Stewardship Green Initiatives In Airfield Pavement Construction Conserve Water Recycle Paving Materials Use of Waste Products Reduce Emissions Reduce Energy Usage
Green Initiatives Conserve Water Recycling of clean-out water at plants Use of storm water for dust suppression or cleaning equipment
Green Initiatives Recycle Paving Materials PCC Pavement HMA Pavement Aggregate Base Products Combination (Mix In-Place and Rubblization)
Green Initiatives Use of Waste Products Flyash in PCC Flyash in Soil Stabilization Polymers or Ground Rubber in Asphalt Binders
Green Initiatives Reduce Emissions Trucking Processing Production (Warm Mix)
Green Initiatives Reduce Energy Usage Trucking Processing Production (Warm Mix) LED Warning Devices
Warm Mix Asphalt WMA reduces temperatures by 35° to 55° F Reducing Energy Usage Reducing Emissions Reducing Worker Exposure Placement Longer Hauls and Lower Temperatures Production Wax Like Products Sasobit, Asphaltan B, Fatty Acid Amides Foaming Processes Aspha-min Zeolite, Low Energy Asphalt, WAM Foam Emulsion Base Evotherm Other Additional Technologies
Economic Growth Economic Growth Cost Savings Strengthen Local and Regional Economies Advance Emerging Markets Integrate Unique Solutions
Social Responsibility Social Responsibility Education (Successful Community Outreach) Fair Labor Practice Reduce Waste Create Public Benefits
BUT We Have Been Doing This RIGHT?
We Don’t Really Know Contractors have been doing this for years as a cost savings measure on projects Owners have benefitted from the “Low” bid process which takes advantage of the Contractor’s cost savings measures
Integration Moving Forward: Review Options During Planning Integrate Options During Design Implement During Construction Most Importantly Allow for Additional Evaluations or Opportunities as Construction Progresses DOCUMENT!
