1.1 These practices cover the calculation of profilograph response to longitudinal profiles of traveled surface roughness.

1.2 These practices utilize computer simulations to obtain profilograph responses including: surface sensing wheel (recording wheel) vertical displacement, and reference platform wheels (supporting wheels) motions, as a function of distance.

1.3 These practices present standard profilograph simulations for use in the calculations.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only and are not considered 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.

5.1 These practices provide a means for evaluating traveled surface-roughness characteristics directly from a measured profile. The calculated output values represent profilograph response to traveled surface roughness.

5.2 These practices provide pavement surface profiles to evaluate pavement condition using the profilograph index.
