1 Pennsylvania Asphalt Pavement Association 54 th 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 2 nd Edition – under revision IS-230; 2 nd 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 E xperiential P articipatory I mage-driven C onnective 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 – 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

10 Current Status - Emulsion Spec Database Status# of States Completed/posted30 Waiting only on final review/approval before posting 13 Collected specs, in process of compiling 2 Not yet started 5

11 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

12 A Cooperative Effort between Asphalt Institute & FHWA Best Practices for Constructing and Specifying HMA Longitudinal Joints A Cooperative Effort between Asphalt Institute & FHWA

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

14 Alaska Some States have more challenges than others!

15 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? “Is Oklahoma satisfied with the long-term performance of your HMA Longitudinal Joints?”

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

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

18 Expected Products or Outcome: 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 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 Explain the WHY! Encourage CHANGE!

20 PA Story on Longitudinal Joint Density Increasing density was viewed as key Increasing density was viewed as key began measuring joint density began measuring joint density method spec. of best practices method spec. of best practices 2008 and continued gathering data on joints 2008 and continued gathering data on joints New joint density specification. Transition year with no bonuses or penalties New joint density specification. Transition year with no bonuses or penalties – bonuses and penalties on joint density – bonuses and penalties on joint density Article in NAPA’s magazine, Asphalt Pavement, Sept/Oct 2012

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

22 -$10,000 PA: Impact on Lot Payment Summary +$5,000 Disincentive PWL Incentive No Pay Adjustment

23 PA: How Did it Work? 94.0% % % 93.9%

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

25 Lots with avg. density <88% G mm require corrective action Lots with avg. density <88% G mm require corrective action Contractor must seal the joint with PG at no cost to Department Contractor must seal the joint with PG at no cost to Department 10 lots required corrective action in lots required corrective action in 2011 PA: Corrective Action

26 Laboratory Quality System New web-based software system for laboratory accreditation with AASHTO

27 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

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

29 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
