Phạm vi áp dụng / Scope of standard

This practice describes a five-point method for estimating
maximum rut depth in asphalt pavement surfaces. Five points are the
minimum number of points, measurement of more points on the
transverse profile enhances the likelihood of identifying the
maximum rut depth.

Note 1-A rut is a longitudinal surface
depression in the wheelpath(s) of a pavement surface.

Procedures are defined for measuring rut depth, but detailed
specifications are not included for equipment or instruments used
to make the measurements. Any equipment, which can measure as
specified, with the accuracy stipulated herein and which can be
adequately calibrated, is acceptable for this method.

This practice does not purport to address all of the safety
issues, if any, associated with its use. It is the responsibility
of the user of this protocol to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations related to and prior to its use.
