Collect pavement profile data between 0-100 mph (0-160). SSI's revolutionary collection system pairs a traditional inertial profiler with additional sensors, allowing for stop-and-go collections in urban areas and traffic. Operators are no longer required to maintain a constant speed while collecting data. Accurate data is now collected through stop signs, intersections, and low speed areas. The Zero-Speed system can be outfitted on any SSI inertial profiler system for DOT, City, County or consultant work.
The Zero-Speed system has been proven on multiple certification tracks under the current AASHTO r56 certification method and the newly proposed stop-and-go certification procedure in California under CTM 387.
Along with the stop-and-go performance, the Zero-Speed profiler also achieves reference profiler level repeatability under ASTM E950.
