SSI - CS8800 Walking Profiler
    Model: CS8800 Walking Profiler
    Country of Origin: Canada
    Use: Collect highly accurate road profiles for ride quality and roughness reporting under agency specifications pavement smoothness testing.  The CS8800 can also generate reliable reference profiles for accuracy comparisons with inertial profilers for equipment certifications. With optional 3D texture and land surveying instrumentation, the CS8800 delivers a highly versatile, productive solution.

Collect Data at Continuous Walking Speed

The CS8800 collects data continuously without stopping the device to record static measurements. Walking speed collections are the norm on regular textured surfaces. The one inch (25.4mm) sampled continuous profiles support outputs far beyond ride indexes, including extensive analysis profile feature and waveband analysis.

Easy to Store & Ship

With a lightweight, compact design and a collapsible handle, the CS8800 ships and stores in a reusable rugged container. Easily transported and ready for use in minutes.

Report IRI & Localized Roughness

The CS8800 has been proven to generate the same results as inertial profilers and the California profilographs. This has been proven by agency certifications and independent research concluding that the CS8800 and inertial profilers generate equivalent profiles, ride quality index results (IRI, PRI, etc.), and areas of localized roughness. The same is true for comparing the CS8800 to the California profilograph--the devices generate equivalent Profile Index and must grind bumps.

Texture Option

Using a wide beam Gocator 5KHz laser from LMI Technologies, the CS8800 is equipped to measure pavement texture. Conventional reporting of Mean Profile Depth (MPD) is supported under such standards as ASTM E-1845 (Standard Practice for Calculating Pavement Macrotexture Mean Profile Depth). 3D laser measurements of the pavement surface are available for viewing and advanced texture analysis. 

Land Surveying Options

The CS8800 can be paired with either RTK corrected GPS or Total Stations instruments. The result is highly accurate one inch sampled surface profile that adds the Z dimension from survey elevations. The data can be converted for use in applications calling for survey formats, such as PNEZD, PLLHD and GPGGA.
