The Dynatest 5051 Mk-III Road Surface Profilometer measures a number of indices and characteristics including the longitudinal profile, International Roughness Index (IRI), Ride Number (RN), transverse profile, rutting, macrotexture, and geometrics (crossfall, gradient and radius of curvature). It can also provide data for the Boeing Bump Index (BBI) calculation. The RSP has a unique “Stop & Go” functionality enabling the equipment to operate in an efficient manner in urban areas, at traffic lights, stop signs, junctions and roundabouts, making it an ideal tool for data collection on both urban and rural networks. The equipment meets the ASTM E950 Class 1, AASHTO R 57 and independently verified State road standards such as the Text-1001-s, ensuring high accuracy, repeatability under a variety of conditions that ensure the data can be used for project and network evaluation and in Pavement Management Systems.

The RSP-III is a fully upgradable system offering up to 21 lasers. Ideal for highways and airports.

The RSP-IV is the portable version easily attached to any vehicle with the capability to attach 1 or 2 lasers. The RSP-IV is extremely versatile, easily mountable on almost any vehicle, for testing Cycle paths determining the Cycle Profile Index (CPI), on highways IRI and RN, and airports to determine the BBI.

Options for both the RSP-III and RSP-IV include texture capable lasers, (D)GPS, and ROW cameras.


– Rapid roughness screening of all network sections

– With the GPS option, all data can be geo-referenced allowing plotting in a GIS system

– “Stop and Go” feature allows for testing of short sections and urban streets, making the RSP an ideal tool for project level as well as network level data collection and analysis

– Operates at traffic speed removing the need for expensive traffic management

– Offers real time data collection, analysis and storage, saving precious engineering time for post-processing of data

– Texture lasers can collect both IRI/RN and macrotexture data simultaneously in a single run

– Automated monitoring of laser readings ensures high quality of data

– Highly accurate, repeatable and reproducible data allowing data to be used in a PMS

– Modular system, is easy to maintain, service and upgrade

– The RSPwin Field program gives step by step guidance for the calibration of lasers, accelerometers and DMI making calibration simple and easy to perform

– The RSP can be upgraded to a Multi-Function Vehicle (MFV)
