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
2nd Edition – under revision
IS-230; 2nd Edition
Under revision
• Expanded sections on oxidation, additives, crude sources
• Expanded references

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

HMA Longitudinal Joints
A Cooperative Effort betweenAsphalt Institute & FHWA
Longitudinal Joints are Still a Challenge for Many Agencies.

AlaskaSome States have more challenges than others!
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?”
The Weakest Link:
Poor Joint Performance is an Agency and Industry

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
• Explain the WHY! • Encourage CHANGE!
PA Story on Longitudinal Joint Density
• 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
Article in NAPA’s magazine, Asphalt Pavement, Sept/Oct 2012http://www.nxtbook.com/nxtbooks/naylor/NAPS0512
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
o For Butt: directly over visible jointo For Notch Wedge: middle of wedge
• Percent Within Limits (PWL) • Incentive starts at 80% PWL • Disincentive at <50% PWL
• Lower Specification Limito 2010-2013: 89% TMDo 2014: 90% TMD
• Corrective action for < 88% TMD

PA: Statewide Pay Impacts Since New Joint Density Spec (2011 - 2013)
• 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
