For many years, SSI’s surface measurement devices have been used on oval and road course race tracks, as well as drag strips. SSI has measured longitudinal profile on NASCAR tracks throughout the USA. Our precise surface data is useful to many—for example racing teams can understand existing track conditions for use in tuning their vehicles for upcoming races; contractors and owners use profile data to make rehabilitation decisions and monitor construction quality.
Racetrack Pavements: High Resolution Point-to-Point Profile Data
SSI’s inertial profiling systems all measure at a configurable sampling interval, set by default to one-inch (25.4 mm). Usually two, but up to five parallel longitudinal profiles can be collected simultaneously. From this detailed scan of the track, changes in the pavement can be assessed with 1 mm or better accuracy. The raw profile data can be processed and reported as desired with SSI or third party application software. The embedded GPS positions can be used to locate and visualize the exact locations depicted within the raw data.
Pavement Condition: Localized Roughness & Features of Interest
The raw data form SSI’s inertial profiling systems can be processed to report pavement features or amplitudes of interest.User configurable templates allow reporting of exact dimensions of bumps and dips exceeding thresholds entered in analysis parameters, or hot spot areas of localized roughness under commonly used DOT specifications. Use GPS within the data to find the exact locations of the features on the racetrack.
Track Rehabilitation: Ride Quality, Topography & Texture
SSI manufactures devices to report pavement ride quality under existing and evolving specifications. The CS8500 California profilograph measures PRI and must grind bumps under longstanding profilograph specifications. The CS9100/CS9300 high speed and CS8700 lightweight inertial profiling systems measure IRI and localized roughness under evolving standards for ride quality based on the International Roughness Index. The CS8800 walking profiler is perfect for drag strip measurement, as it outputs both profilograph and inertial profiler reports for all commonly used ride and roughness specifications. Optional instrumentation is available on all devices to report 2D or 3D formatted survey data, cross-slope and pavement texture.
