PORTABLE ROAD SURFACE PROFILER (RSP) MARK IV
PORTABLE ROAD SURFACE PROFILER (RSP) MARK IV
The Dynatest Portable Road Surface Profiler (RSP) Mark IV is an advanced tool designed for high-quality pavement roughness measurements. It is portable and can be easily mounted on most vehicles, providing real-time, continuous measurements at highway speeds.
The RSP Mark IV uses the 'South Dakota' method, employing an accelerometer for vertical vehicle body movement and a laser sensor for measuring displacement between the vehicle and pavement. The International Roughness Index (IRI) is calculated following World Bank guidelines.
The device complies with several standards, including AASHTO R 56-14, ASTM E950/E950M-09, and TxDOT Tex-1001-S, ensuring precision and reliability in measurements.
- Accurate and dependable with long-term calibration stability.
- 'Stop & Go' feature for data collection in various traffic conditions.
- Adjustable laser sensors for different widths and optional GPS and digital photo logging.
- Solid construction with corrosion-resistant materials for durability.
- Allows IRI measurements at all traffic speeds, including challenging areas like junctions and roundabouts.
- In-field vertical alignment for optimal laser mounting.
- Vehicle-independent system that is easy to mount and remove.
- High precision with standard 5G accelerometers and built-in analysis software.
The system is powered by a vehicle's standard 12V connection and features Ethernet communication for data transfer. Dynatest provides 24/7 technical support.

■ MEASURING PRINCIPLE The longitudinal profile measurement is based on the “South Dakota” method. An accelerometer is used to obtain vertical vehicle body movement, and a laser sensor is used for measuring the displacement between the vehicle body and the pavement. Road profile measurements are obtained by summing the body movement with the appropriate body-road displacements. IRI is calculated in accordance with Word Bank guidelines for “Conducting and Calibrating Road Roughness Measurements”. ■ COMPLIANCE WITH INDUSTRY STANDARDS AASHTO R 56-14 “Standard Practice for Certification of Inertial...
