Scope
The objective of this specification is to define the required attributes of an inertial profiler@ which@ when combined with an operator@ becomes a complete inertial profiling system (IPS). The system may be used to measure a longitudinal pavement profile for construction quality control and acceptance or for network data collection. The equipment may be added to a host vehicle as a single-function device or a component of a multifunctional data collection device. The equipment 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 equipment shall be capable of outputting the pavement elevation profile as a temporary display@ a printed record@ and 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 profilers will be identical.
