    1. “Going Green” 2010 Northeast Association of State Transportation Officials Annual Meeting (NASTO) June 13, 2010 Wilmington, DE Jim Pappas DelDOT Materials & Research

    2. 2010 NASTO - Going Green…. National (AASHTO SOM Recycling Task Force) and local perspective on construction materials recycling for DOT’s….. “The greatest gap in life is the one between knowing and doing.” Dick Biggs

    3. Construction Materials Recycling Why? Impediments to implementation Overcoming obstacles What materials to use? DelDOT experience Challenge

    4. Why Recycle? Psychological – “feel good” Environmental benefits – no land filling Save finite natural resources Engineering benefits Lower greenhouse gas emissions (less trucking) It makes cents…. (and $$)!

    5. Impediments to Implementation Misconceptions Bad (past) experiences Lack of knowledge Regulatory challenges Department (Agency)/Contractor willingness “Success is measured by your ability to maintain enthusiasm between failures.” Winston Churchill

    6. How to Overcome? Outreach/marketing Educate Research work (FHWA, AASHTO, NCHRP, Industry, etc). University research Highlight state’s/contractor’s successes

    7. How to Overcome? (cont) Partnerships Industry (NAPA, ACI, PCA, ARRA, etc) Environmentalists Planners Designers Elected Officials/Public Materials/Construction groups FHWA, AASHTO University researchers

    8. Research Activities FHWA RAP ETG TRB – Energy and Environmental Workshop EPA Green Highway Partnership (GHP) Mid-Atlantic Specification Harmonization

    9. GHP Harmonization Materials Foundry Sand Recycled Asphalt Pavement Fly Ash/Bottom Ash Scrap Tires Steel Slag Scrap Shingles

    10. DelDOT Experiences Materials Recycled Asphalt Pavement (RAP) Recycled Asphalt Shingles (RAS) Ground Granulated Blast Furnace Slag (GGBFS) Warm-Mix Asphalt (WMA) Recycled Concrete Aggregate (RCA) Fly Ash (embankment, concrete) Tires (embankment, HMA)

    11. DelDOT Experiences (cont) Pavement Systems Cold-in-Place Recycling (CIPR) Full-Depth Reclamation (FDR) Saves natural resources Reuse good materials Less trucking (GHG savings)

    12. Challenge…… Take something you’ve heard today, and try to implement it in your state. “It is hard to fail, but it is worse never to have tried to succeed …. he who makes no mistake makes no progress.” Theodore Roosevelt

    13. “If we knew what we were doing, it wouldn’t be called research.” Albert Einstein

    14. Thank you for your time and attention Jim Pappas 302.760.2400 James.pappas@state.de.us
