  1. Pennsylvania Asphalt Pavement Association54th Annual Meeting Asphalt Institute Initiatives January 29, 2014 Peter T. Grass, P.E., CAE

  2. Clinten “Clint” J. Rybak • Phillips 66 Company • AI Chairman • 2014 • Steve Smithey • BP Asphalt • AI Vice Chairman • 2014

  3. IARC Review – Positive Outcomes • Focus on “Occupational Exposure” • Inadequate Evidence re. Straight Run • Recognized “air rectified” as Distinct • Exposures Declining Over Time • Industry-sponsored Research Respected • No “Environmental” Concerns Identified • Clear separation from coal tar • Natural bitumen outside scope of review • Application temperature recognized as factor

  4. 2nd Edition – under revision • IS-230; 2nd Edition • Under revision • Expanded sections on oxidation, additives, crude sources • Expanded references • Available in print and PDF format since March 2011 • AI or Eurobitume’s websites

  5. NBTC Progress • Yellow: agencies & suppliers • Brown: agencies only • Green: suppliers only • Grey: opportunity!

  6. EPIC 2014 - 2015 Experiential Participatory Image-driven Connective 2014 – 2105 Class forming • 3 of 4 facility tours • Elective options • Writing assignment • Group project • Graduation Spring 2015

  7. Burn First Responder Safety! • US Burn Center research – 2011-2013 • Focus on first aid, first responder actions • Workplace posters, wallet cards • Medical paper headed to peer reviewed journal

  8. Screenshot – AI’s Public Homepage Binder Specs Emulsion Specs

  9. Current Status - Emulsion Spec Database

  10. Binder Spec Database Recently Enhanced as Well • New and Improved Format • Completed for all 50 States (3 mb pdf files) • More uniform template across all States • PG Testing on Page 1 • PG+ Testing on Page 2 • Grey out tests that are not required • Easier to maintain, better aesthetics and utility • Vastly improved footnoting

  11. Best Practices forConstructing and Specifying HMA Longitudinal JointsA Cooperative Effort betweenAsphalt Institute & FHWA

  12. Longitudinal Joints are Still a Challenge for Many Agencies. Photo by James Scherocman, P.E

  13. Some States have more challenges than others! Alaska

  14. “Is Oklahoma satisfied with the long-term performance of your HMA Longitudinal Joints?” Question? If the Answer is NO or not totally; then – What can you do as an Agency? What can you do as a Contractor/Industry? What can you do as a Equipment Manufacturer? What can you do as a Researcher?

  15. The Weakest Link: Poor Joint Performance is an Agency and Industry Concern

  16. Longitudinal Joint Workshops (4-hrs) FHWA/AI Cooperative Agreement 1-27-2014 NH WA MT ME VT MN ND WV ID (2) MA NY (2) OR SD RI W I MI PA CT WY IA OH UT IN IL NJ NE MO DE NV (2) MD CO KS KY DC TN NC AR VA CA OK SC AZ NM AL GA MS LA FL PR AK TX Workshops Held (35 in 30 States) Workshops Scheduled (3 States) HI AK HI

  17. Create Greater Awareness Improve Specs by Agencies Increase use of Innovative techniques, equipment, and materials Improve practices by Contractors Overall Improved LJ Performance Fewer incidences of shortened pavement life Expected Products or Outcome: • Explain the WHY! • Encourage CHANGE!

  18. PA Story on Longitudinal Joint Density Article in NAPA’s magazine, Asphalt Pavement, Sept/Oct 2012 http://www.nxtbook.com/nxtbooks/naylor/NAPS0512 • Increasing density was viewed as key • 2007 - began measuring joint density • 2008 - method spec. of best practices • 2008 and 2009 - continued gathering data on joints • 2010 - New joint density specification. Transition year with no bonuses or penalties. • 2011-2014 – bonuses and penalties on joint density

  19. PA Joint Density Spec Highlights • Both type of LJs allowed (butt or notch wedge) • Joint Lot = 12,500’. Core every 2,500’. 5 cores per lot. • Core location • For Butt: directly over visible joint • For Notch Wedge: middle of wedge • Percent Within Limits (PWL) • Incentive starts at 80% PWL • Disincentive at <50% PWL • Lower Specification Limit • 2010-2013: 89% TMD • 2014: 90% TMD • Corrective action for < 88% TMD

  20. PA: Impact on Lot Payment Summary +$5,000 -$10,000 Disincentive Incentive No Pay Adjustment 0 50 80 100 PWL

  21. PA: How Did it Work? 162 94.0% 91.6% 2013 167 91.4% 93.9%

  22. PA: Statewide Pay Impacts Since New Joint Density Spec (2011 - 2013) 2011 - $261,625 in bonuses - $99,216 in penalties 2012 - $468,300 in bonuses - $62,976 in penalties 2013 - $588,247 in bonuses - $24,720 in penalties

  23. PA: Corrective Action Lots with avg. density <88% Gmm require corrective action Contractor must seal the joint with PG 64-22 at no cost to Department 10 lots required corrective action in 2011

  24. Laboratory Quality System • New web-based software system for laboratory accreditation with AASHTO

  25. Asphalt Academy seminars Binder Technology Basic Binder Technician Training National Binder Technician Certification Program Mix Design Technology Certification Principles of Quality HMA Pavement Construction An Introduction to the Bailey Method Airport Pavement Workshop Hot Mix Asphalt 101

  26. AI’s Laboratory HVAC Replacement - 2013 • Project is complete • Started May ‘13 • Resumed normal lab operations in October ‘13 • Teaching lab – mix design, binders, NBTC • Research, commercial binder testing

  27. AI – Running Strong! • Membership • 128 members • 95 % of liquid produced in North America • Voice of liquid industry • Member engagement at all time high • Growing International presence

  28. 2014 Asphalt Institute Members
