Pavement Walking Profiler

Pavement Walking Profiler

This high-precision walking profilometer is designed with an imported angular sensor & tablet. The pavement longitudinal profile can be measured during operator push-walking at normal speeds up to 3km/hr, then outputs such as IRI and SMTD(MPD) can be produced through calculation of mathematical models.
The walking profiometer can be widely used for inspecting quality of pavements, footpaths, tunnels, airport runways and building slabs, or being reference tool for calibrating & assessing for vehicle type high speed profilers.
Portable in small size, simple operation.
Detecting system is connected to tablet by Wi-Fi.
Real-time results of IRI and MPD index & curve are displayed on tablet screen, which can be printed on site immediately.
Data acquisition & processing is performed by tablet.
Comparing with vehicle-mounted laser profiler, this walking-profiler detecting speed is slower, but the detection accuracy is higher.
