Overview

SSI has multiple devices that comply with existing and evolving airfield pavement smoothness specifications. For decades, the SSI-Cox CS8200/CS8500 profilograph systems have been the standard equipment used on airfield pavements worldwide. SSI inertial profilers fully comply with developing IRI specifications for airfield quality testing. With available reporting of Boeing bump test and pavement wavelength features according to user specified thresholds, SSI’s devices provide sophisticated information about conditions affecting aircraft interaction with airfield pavements.  

 

Airfield Pavement Roughness

SSI’s CS8500 California profilograph has been used on airfield pavements Worldwide. SSI’s CS8700 lightweight and CS9100/CS9300 high speed inertial profilers measure pavement elevations at a default 1 inch (25 mm) sampling interval. The CS8800 walking profiler measures a precise profile from a dead stop (no lead in or run out required); as such, the CS8800 is perfect for transverse airfield pavement measurement. The raw data can be processed to report ride indexes, including Profile Ride Index (PRI, profilograph), IRI (International Roughness Index), and areas of localized roughness (either profilograph style “must-grind” bumps or high concentrations of IRI threshold roughness). Boeing Bump Test reporting is also reported.

 

Airfield Pavement Features

The raw profile data recorded by SSI’s inertial profiling systems can be analyzed to report features of interest or relevance to aircraft dynamics.  Short, medium or long waveband features can be ascertained. The raw profile data can be processed to assess characteristics from very short features--such as birdbaths--to very long amplitude conditions affecting aircraft dynamics.  Templates are provided for identifying peak or trough amplitudes exceeding of thresholds as configured by the user. Once you have the highly accurate and detailed pavement profile data from an SSI inertial profiler, extensive analysis and reporting is provided within our Profiler 3 software.

 

3D Survey & Pavement Texture

3D survey format data is available using SSI’s GeoProfiler devices, which are integrate inertial profiler data with cross-slope and RTK corrected GPS. The GeoProfiler are vehicle mounted lightweight or high speed inertial profilers that are capable of collecting dense topographies and cross-sectional data in a fraction of the time taken for traditional survey equipment. The CS8800 walking profile can be paired with total stations devices for an extremely accurate pavement profile including survey elevations. All of SSI’s survey-profile systems support CAD format outputs (PNEZD, PLLHD and GPGGA) for use with third party pavement design and machine control applications.
