Road texture measurement system

Pavement Texture Measured Efficiently with FLaSH

M+P’s family of FLaSH TEXTURE systems is designed to accurately capture and analyse texture data. Measuring road textures with FLaSH TEXTURE is a straightforward process. FLaSH TEXTURE analysis is clear and yields solid, reproducible results.

Road texture is an important property that provides civil and acoustic engineers with valuable information about road noise, fuel consumption, wet skid resistance and road maintenance.

The results of the analysis with TextureInspector are common texture indicators such as MPD (Mean Profile Depth), ETD (Estimated Texture Depth), RMS and skewness. In addition TextureInspector calculates texture wavelength spectra.

M+P has performed mobile in-traffic measurements of road textures for many years. Based on our experience, we have developed a measurement system that gets the job done accurately and safely. Mounting is easy and the user interface is tailored for on-the-road use.

FLasH measurement systems

FLaSH|M is a rugged system that efficiently captures many kilometers of pavement texture profile. In normal traffic at speeds of up to 100 km/h, FLaSH|M records the road textures at a rate of one sample per millimeter.
During data capture, the operator can at-a-glance monitor the signal quality and insert location markers that will be available during the analysis of the profile-data. After recording, the captured data can be fed into TextureInspector for easy data selection and analysis according to the ISO 13473 series.

FLaSH|S is a turnkey system for measuring pavement textures, whether on-site or in a lab environment.
A precision portal beam moves a laser-based profile sensor across the road surface measuring the 3D depth profile of the pavement.
The captured data can be immediately viewed and analysed. The analysis returns common texture indicators such as MPD, ETD, RMS and skewness.
