International Cybernetics Corp

Our ICC 3D Imaging System uses high-speed cameras, custom optics and laser
line projectors to acquire both 2D images and high-resolution 3D profiles of the roadway.


Faulting is the variation in elevation across a joint or crack. The elevation difference is typically caused by pumping, which causes a step up or down from the departure slab to the approach slab. The height of the step is measured from the longitudinal profile. For a fault reading to be considered a fault, it must exceed a specified minimum height (default value is 0.1 inch). The algorithm ensures that extraneous readings are removed.

ICC provides fault measurement solutions for roadway or bridge analysis.

The individual fault points are recorded in a file with an .F extension. The format of the data is comma delimited consisting of:

  • Reference post
  • Left or drivers side fault measurement
  • Right or passenger side fault measurement

The fault index is calculated and reported for each wheel path.

Faulting can be measured by both the ICC profiler and the 3D Imaging System.  These systems can be operated day or night. All pavement types, including regular and open-graded asphalt, chip seal and concrete, can be measured at survey speeds up to 100km/h and covering approximately 4 meters transversely across the lane.

Longitudinal Profilers

The International Cybernetics Corporation on MDR408x family of road profilers are precision, non-contact ASTM E950 Class 1 pavement profilers. These systems primarily consist of infrared laser height sensor(s), precision accelerometer(s), a distance measuring unit and an industrial hardened IBM compatible PC. The complete system is state of the art, composed of hardware and so+ware that is mounted into a vehicle according to the customer’s data collection needs. The profilers can be configured with multiply height sensors, single or dual accelerometers and any subsystem the client wishes. The profiler is primarily used to rate pavement ride (IRI, PI, RN, Rolling

Straightedge), rutting, texture and faulting. In addition, the system will produce a profilograph simulation with bump / dip locations and must grind lines.
