    8300 Survey Pro High Speed Profiler

    System Overview:

    The Model 8300 Survey Pro High Speed Profiler is designed for those interested in collecting macro surface texture data along with standard profile data. Using the same chassis and sub-assembly as our standard high speed unit the operator can simply replace the standard sensor with our texture sensor allowing them to measure both macro surface texture and longtitudinal profile at highway speeds. Using our custom software the operator is then able to calculate multiple texture indices such as Mean Profile Depth (MPD).

    • High Speed system mounted on front or rear hitch of vehicle; standard 2” hitch receiver
    • Ruggedized laptop mounted in cab of vehicle with test personnel
    • Single or dual laser systems are available
    • High speed mounting hardware is height adjustable for different vehicles

    Developed for:

    • Paving contractors
    • Testing agencies
    • State and federal highway departments

    Texture Specifications:

      • Laser height sensor with a range of 180 mm and a resolution of 0.045 mm
      • Horizontal distance measured with an optical encoder that has a resolution of 1.2 mm
      • Pavement elevation sampling: 62,500 samples per second
      • Profile wavelength down to: 0.5 mm

    Profiler Specifications:

      • Capable of collecting measurements at speeds between 25 and 70 mph (40 and 95 kph)
      • Laser height sensor with a range of eight inches and a resolution of 0.002 inch (0.05 mm)
      • Horizontal distance measured with an optical encoder that has a resolution of 0.15 inches (3.8 mm)
      • Horizontal distance can also be measured with a Speed Sensor or non-contact Doppler sensor which has a resolution of 0.2 inches
      • Pavement elevation sampling: 16,000 samples per second
      • Pavement elevation sample storage: software selectable 1-16 samples foot

      • Data interchange: Secure Digital PC card

    Texture Software:

      • Microsoft Windows operating system
      • Display profile in real time while data is being collected
      • Post process software performs the conversion from the time-domain to spatial-domain which allows for accurate Mean Profile Depth (MPD) measurements to be calculated
      • Raw data format can be output in CSV format for the time or spatial domain. Raw data can also be output in the spatial domain for ERD or PRO file formats. These formats can be imported into ProVal or Road Rough software applications
      • High and low pass filtering can be applied to the raw data to allow the user to focus on wavelengths of interest within the macro-texture waveband

    Profiler Software:

      • Microsoft Windows operating system
      • Display profile in real time while data is being collected
      • Calculates Profile Index (PI), International Roughness Index (IRI), Half-car Roughness Index (HRI), Ride Quality Index (RQI), and Ride Number (RN)
      • Plots true profile, California profilograph profile, and rolling straightedge profile
      • Equipped with variable high and low pass filter options
      • Contains automatic bump detection software
      • Capable of displaying “true” profile, rolling straightedge, and California type profilograph profile on screen
      • Identifies location of “out-of-specification” bumps and dips
      • Bumps can be located easily using system’s odometer mode
      • Equipped with the following export file options: profile elevation points, Michigan ERD format, Texas PRO format, comma separated variable (CSV) format and generated report tables format (HTML)
