Standard Equipment Specification for Inertial Profiler
standard by American Association of State and Highway Transportation Officials, 2010



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 systemmay be used to measure a longitudinal pavement profile for construction quality control andacceptance or for network data collection. The equipment may be added to a host vehicle as asingle-function device or a component of a multifunctional data collection device. The equipmentshall be able to calculate summary roughness indices, particularly the International RoughnessIndex (IRI). This specification is designed to apply to both low-speed and high-speed profilers.
