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 ...
