Ensuring Quality Data from Inertial Profilers
Inertial profilers are a key component in the collection of pavement performance testing. They allow large amounts of testing, while travelling at the posted speed limit to ensure safety and the impact on traffic flow. However, the equipment is composed of a range of sensors that collect data and need to be used together to calculate values such as the International Roughness Index, rutting, and other automated condition indices. There are several standards that outline the equipment and testing procedures required. Many of these standards classify the vehicle, provide details on how the analysis is done, and procedures for calibration and quality testing. However there are many other steps that can, and should, be taken in order to sure the data is tested accurately and consistently across the entire network. This paper describes the types of quality control procedures that are recommended for inertial profiling. They describe the benchmark testing of the equipment, applicable standards, and routine equipment checks that should be complete. Also discussed is the development and testing of project control sites, interpretation of the data to ensure quality data collection. The procedures described are based on extensive testing experience and a range of agency specifications for data collection.
