Specifications include, but are not limited to: These specifications are for a portable, vehicle mounted, high speed inertial profiling system that also provides rut measurement and image capture capabilities.
The system shall:
Meet the applicable requirements of AASHTO M328, R56 and R57 for high speed profilers.
Be designed so that all major equipment components may be easily removed from the host vehicle.
Generate rut-depth measurement values consistent with AASHTO R48-10.
Be capable of determining a profile value (sampling interval) every 1.0 in. or less at the maximum collection speed of the vehicle.
Be capable of generating profile data files in a format compatible with Profile Viewing and Analysis (ProVAL) software.
Provide GPS coordinates for collected data with at least 1m accuracy.
Include line lasers with a minimum 4-inch footprint for the wheelpath positions.
Include a right-of-way (ROW) camera system that collects HD images at user specified intervals or positions.
