  1. Rubber Tire Buildup Removal at Hartsfield-Jackson Atlanta International Airport Quintin Watkins,P.E. Prime Engineering, Inc., Atlanta, GA Rick Boudreau, P.E. Boudreau Engineering, Atlanta, GA Rob Rau, CM and Heinz Hansen, CM Hartsfield-Jackson Atlanta International Airport 2010 FAA Worldwide Airport Technology Transfer Conference April 20-22, 2010, Atlantic City, New Jersey, USA

  2. HARTSFIELD-JACKSON ATLANTA INTERNATIONAL AIRPORT • 5 Runways • 2 Arrivals – • 9L (1972) & 8R (2006) • 2 Departures – • 9R (1999) & 8L (1984) • 1 Mixed – • 10/28 (2006) • 1,400 Peak Daily Arrivals • 400,000 Landing Ops per year

  3. WHY MEASURE FRICTION ON RUNWAYS? • “Contaminants, such as rubber deposits, dust particles, jet fuel, oil spillage, water, snow, ice and slush, all cause friction loss on runway pavement surfaces.” • “The most persistent contaminant problem is deposit of rubber from tires of landing jet aircraft” • “Heavy rubber deposits can completely cover the pavement surface texture causing loss of aircraft braking capability and directional control, particularly when runways are wet.” • Source: FAA AC 150/5320-12C Paragraph 3-1

  4. SARSYS FRICTION TESTER - SFT (SCANDINAVIAN AIRPORT AND ROAD SYSTEMS) • CFME- Continuous Friction Measuring Equipment • The “Mu Value” is calculated by the horizontal force divided by the vertical force or by using the measured torque generated at the measuring tire. • Runway friction coefficient (property of micro and macro surface) SAAB 9-5 SAAB 9000

  5. TESTING PROCEDURE • “Friction surveys should be conducted 10 and 20 feet to the right of the runway centerline to determine the worst case condition.” • “The SFT is equipped with a self-wetting system to simulate rain wet pavement surface conditions and provide the operator with a continuous record of friction values along the length of the runway.” • Source: FAA AC 150/5320-12C Paragraph 3-15(a)

  6. TESTING FREQUENCY & REQUIRED Mu VALUES • FRICTION TESTING CONDUCTED ON • Arrival Runways BIWEEKLY • 8L-26R, 9R-27L, 10-28 • Departure Runways QUARTERLY • 8R-26L, 9L-27R • Minimum Friction Level - .50 • Maintenance Planning Friction Level - .60 • Source: FAA AC 150/5320-12C Table 3-2 ‘FRICTION LEVEL CLASSIFICATION FOR RUNWAY PAVEMENT SURFACES

  7. Runway 8R-26L Mu Values at Opening 2006 Mu = 0.80 at opening

  8. RUNWAY PAVEMENT MAINTENANCE & REMOVAL SCHEDULE No Maintenance required on Runway 9L C- Chemical Removal S- Shot Blast R- Regrooved

  9. Runway 9R-27L Mu Values before Chemical Removal

  10. Runway 9R-27L Mu Values after Chemical Removal

  11. Runway 9R-27L Mu Values before Shot Blasting

  12. Runway 9R-27L Mu Values after Shot Blasting

  13. Conclusions • Hartsfield-Jackson Atlanta International Airport • Uses a combination of • Chemical Removal average Friction Value of 0.80 • Shot Blasting average Friction Value of 0.90
