The RSP is capable of real-time, continuous, highway-speed measurements of longitudinal profile elevations, International Roughness Index (IRI), slab faulting, and texture. The RSP’s longitudinal profile measurement is based on the South Dakota method. The system allows the operator to view real-time profile data in both wheel paths in a graphical display allowing for verification of data collection.

• Meets the Class I specifications as defined by ASTM E-950 and the Texas Transportation Institute
