摘要：	The phenomenon of runway rouchdown zone rubber buildup is apotentially hazardous proble.Rubber covers the runway surface and occludes the surface texture.This results in reduced wet friction coefficient between the run way pavement and the aircraft tires. Methods and equipment are available for evaluating the wet friction coefficient; however,these methods are expensive and require highly trained personnel. Therefore most airport and airbase managers rely exclusively on visual impressions on rubber buildup in lieu of quantitative measurements. Nonetheless,evaluation techniques are desireable for evaluating rubber buildup.An extensive literature review suggests that pavement surface texture measurement techniques may be indicative of rubber buildup and resultant reduction in wet friction coefficient.Rubber buildup alters the texture properties of a runway as well as the frictional coefficient. A suggested field evaluation experiment is described in this report to ascertain which of five selected texture measurement techniques are indicative of reduced friction values in pavement areas with rubber buldup. This field experiment is designed to provide quantitative methods for ascertaining rubber buidup.This experiment will also aid in the development of contract specifications for rubber removal.
