Work Plan for FY2005

• Continuation and Completion of Current Projects
• Moisture curling -- complete goals in FY2005
• Fatigue in Airport Pavement -- current student is
  near graduation, but could be extended with new
  objectives with a new student
• NAPTF material testing -- extendable with new
  objectives
• Flexible Overlays -- extend with new focus move
  toward design and implementation
• Fatigue and Fracture -- NU student near
  graduation FY2005 to complete project goals
• Internship Program -- open program to other
  schools with minority populations

Work Plan for FY2005

• New ideas
• High Performance Concrete for Airport Pavements
• We see reduced slab sizes, greater conservativism
  driven by unpredictability of materials
• Today Flex strength is main parameter--
  INADEQUATE.
• Future Consider other material behavior --
  fracture, agg interlock, fibers, dowel issues,
  admixtures
• Implementation of Superpave mix designs for FAA
• Antioxidants in asphalts for enhanced durability
  -- additives reduce oxidation and embrittlement
• Performance based guide for hot-poured crack
  sealants
• 3-D analysis and modeling of asphalt materials
• 3-D analysis of aircraft loading pulse
• Integration of Denver data, ATLaS, NAPTF data
• Pavement Mgmt System for National Airports
• Improved methods for pavement condition
  assessment, NDT (e.g GPR), uniform stds and
  software
• Winter maintenance, skid resistance

The New Center

• FAA and OMP are two major sponsors
• Project costs separate and accountable
• Center objectives unified and leveraged
• Leverage and Collaboration
• Share administrative costs
• Common research goals
• Complementary Outreach Program
• Greater visibility of Center activities
