  1. Anti-icing Study at O’Hare International AirportProfessor: Barry J. DempseyGraduate Asst.: Nathan M. Carroll

  2. BRIEF HISTORY • Winter of 2002, phase I testing began on textured aggregate coatings. • These Anti-icing Smart Pavement Overlays were evaluated for durability. • Preliminary observations demonstrate feasibility of installation process and durability. • Phase II began with installation of observation bed at O’Hare.

  3. THE THEORY • The pavement overlay is placed on an existing pavement surface. • Anti-icing chemical is applied prior to icing conditions. • Icing conditions occur. • Anti-icing chemical are released from pavement. • Ice melts.

  4. OUR GOAL • To perform a comprehensive observation of the test pavement under controlled conditions. • To perform complete analysis of all recovered data to determine the durability, performance and surface friction characteristics of the anti-icing pavement.

  5. OBSERVATIONS • Visual Conditions • Weather Conditions • Surface Temperature • Operations & Maintenance

  6. Visual • On-sight observation of entire test bed. • Photographic documentation. • Real time video feed of taxiway (24/7).

  7. Weather Conditions • Daily climatic data collected from NOAA. • Climatic data utilized in the Enhanced Climatic Model (ECM). • Surface temperatures monitored with existing sensors.

  8. Operations and Maintenance • Use of observational video to determine all activities that occur on the pavement along with quantity and duration of activities. • Documentation of O & M’s daily log of activities for correlation with video observation.

  9. Equipment: De-icer and Brushes

  10. INITIAL ACTIVITES • Camera system installed and fully operational by end of October • Run friction tests to establish baseline for anti-icing pavement and control. • Take core samples from test site

  11. TIMELINE • November 1, 2004 • Begin complete observations of test pavement • January 1, 2005 • Submit interim report on findings • April 1, 2005 • Begin intense analysis of all accumulated data • August 2005 • Submit Final Report
