Overview of FAA COE Program: Pavement Research and Airport Infrastructure Developments

This document provides an overview of the FAA COE Program presented by David A. Lange at the University of Illinois at Urbana-Champaign on October 7, 2004. It covers key research areas for FY2004, including moisture curling of concrete slabs, fatigue in airport pavements, and advanced model development for flexible overlay systems. Additional topics include anti-icing coatings, wildlife research, and internship programs for minority graduate students. The work plan for FY2005 outlines the continuation of significant projects and new research initiatives aimed at enhancing airport pavement performance and resilience.

  1. FAA COE Program Review David A. Lange University of Illinois at Urbana-Champaign October 7, 2004

  2. Overview of FY2004 Program • Pavement Research Program • Moisture curling of concrete slabs for airfield applications • D.A. Lange and J.R. Roesler • Fatigue in Airport Pavements • S.H. Carpenter • Materials Testing for NAPTF Base/Subbase and Subgrade Layers • E.Tutumluer • Design of Flexible Overlay Systems for Asphalt Pavements: Phase II Advanced Model Development • W.G. Buttlar • Fatigue and Fracture Behavior of Airfield Concrete Slabs • S.P. Shah, B. Mu, J.R. Roesler • Added Project • Anti-icing Coating Self Cleaning Properties and Wearing Characteristics Study at ORD • B.J. Dempsey • Wildlife Research Program • Bird Strike Advisory System • Ed Herricks • Outreach Program • Summer COE Internship Program for Minority Graduate Students • B.J. Dempsey

  3. 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

  4. 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

  5. Latest news on OMP • Contract with OMP is assured; work underway • 2004-5 program • Research • Subgrade stabilization • Raw materials • PCC Mix Designs • Outreach • Minority- and Women-Owned Businesses • Continuing education • Co-op internship program • Kickoff meeting on Oct 28, 2004

  6. 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
