Development and Evaluation of New Calibration Site, Tyndall AFB, for Continuous Friction Measurement Equipment

Abstract

The Air Force Civil Engineering Center (AFCEC) has been measuring military runway pavement friction and texture conditions around the world for many years. In recent years, the friction measurements have been collected using seven GripTester (GT) trailers, and pavement texture measurements using the NASA grease sample method (ref. 1). The main purpose of developing a calibration site at Tyndall AFB, Florida, is to provide an efficient way to maintain the seven GTs within calibration limits and to provide a range of test surface textures for measurement with different, more efficient equipment than the NASA grease sample method. Hence the scope of this contract project between USAF AFCEC and Chemtek/AeroGroup involved: 1. obtaining six different calibration test surfaces; 2. collecting data using seven USAF GTs, a Dynamic Friction Tester (DFT), a CT meter and a HTD meter; 3. correlating these friction and texture measurement; and 4. determining the International Friction Index (IFI) values. The work of achieving the six calibration test surfaces was completed in June 2015 using the Skidabrader machine. Five of the USAF GTs were evaluated together with the HTD meter in late June, early July 2015. In August 2015, the DFT and the CT meter collected friction and texture data on the six test surfaces. In October 2015, data was collected on the six calibration surfaces with the other two USAF GTs. The following sections of this report will describe the calibration site surfaces, the test equipment and procedures used, the data collection, analysis and reduction, determination of the IFI values, the data correlation with several conclusions and recommendations are given as well as a list of appropriate references.
