Scope of standard 1.1 This practice covers the calculation of mean profile depth from a profile of pavement macrotexture. 1.2 The mean profile depth has been shown to be useful in predicting the speed constant (gradient) of wet pavement friction. 1.3 A linear transformation of the mean profile depth can provide an estimate of the mean texture depth measured according to Test Method E 965. 1.4 The values stated in SI (metric) units are to be regarded as standard. The inch-pound equivalents are rationalized, rather than exact mathematical conversions. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
