Asphalt pavement Walking Profilometer for collecting surface condition information

Pavement Walking Profilometer

Model : MP

I.Measurable Parameters
-.International Roughness Index(IRI)is an indicator used world wide for the characterization of longitudinal road roughness. This study summarized IRI limit values for new, reconstructed or rehabilitated roads, forin-service (existing) roads and road classification schemes used around the world.
-.Flatness standard deviation(σ):standard deviation of the flatness adopt continuous flatness meter to measure the standard deviation of unflatness, represents the flatness of the road surface.
-.Ride Number (RN )The Ride Number(RN) is a mathematical processing of longitudinal profiles that allows the estimation of the subjective ride quality perceived by road users
-.Ride Quality Index (RQI)
