Abstract:

The phenomenon of runway touchdown zone rubber buildup is a potentially hazardous problem. Rubber buildup covers the runway surface and occuludes the surface texture. This results in a reduced wet friction coefficient between the runway and the aircraft tires. Presently, methods and equipment available for evaluating the wet friction coefficient are expensive and require highly trained personnel. Therefore, most airport and airbase managers rely exclusively on visual impressions of rubber buildup in lieu of quantitative measures. The use of pavement surface texture measurements is generally thought capable of determining pavement friction levels. This report discusses use of four economical texture measurement techniques and their relationship to friction levels as determined by the Mu-Meter. Good correlations were obtained by relating pavement surface texture measurements to friction. However, predictive errors preclude the use of these models in lieu of friction measurements for use in rubber removal guidelines. Keywords Stereophotography Hydroplaning.
