ASTM E1845 : 09

Standard Practice for Calculating Pavement Macrotexture Mean Profile Depth

Standard Details

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 E965.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
