Phạm vi áp dụng / Scope of standard

The objective of this specification is to define the required
attributes of an inertial profiling system (IPS) to measure a
longitudinal pavement profile for construction quality control and
acceptance. The system shall be able to calculate summary roughness
indices, particularly the International Roughness Index (IRI). This
specification is designed to apply to both low-speed and high-speed
profilers.

The system shall be capable of outputting the profile as a
temporary display, a printed record, or a data file.

It is not the intent of this specification to relieve the
supplier from the final responsibility to provide an appropriate
product for the intended function nor is it intended to specify all
the design details. The objective is to provide a sufficiently
detailed specification that the function is clearly defined. It is
intended to be sufficiently detailed that the data collected from
multiple systems will be identical.
