TextureInspector was tested in the field during April 2015

This summer M+P has launched a new measurement system: FLaSH. FLaSH determines the pavement texture according to ISO 13473. A smooth surface texture results in a reduction of both road traffic noise and fuel consumption. An important part of FLaSH is Texture Inspector. Texture Inspector is a stand alone application and it post-processes all the data gathered during the measurements.

The results of Texture Inspector can be used to determine if the initial pavement texture meets a specific value stipulated in a contract. Another application is monitoring the degeneration of the pavement texture. This could trigger maintenance or replacement.

The first working version of 'texture inspector' dates from a few years back. It did consist of binary files, textfiles, excelfiles, and matlabscripts. These scripts had to be customized for each project. Furthermore it did require a lot of programming expertise and a solid scientific background in acoustics to both execute the measurements as to do the analysis. Peer reviews were necessary to avoid an occasional error to enter the final report. Texture inspector will remove all these restrictions except for the necessary acoustical background.

Texture Inspector has five major screens:

  1. Project, where you can enter all project characteristcs (e.g. projectname, projectnumber, roadnumber).
  2. Data import, where you can import each datafile that was made during the measurements. Currently 3 input file formats are supported.
  3. Data selection, where you can select which parts of the raw data must be analyzed further. The selection can be made with both a mouse (graph) and a key board (numeric table).
  4. Analysis, where you can assess the resampled data. The resampled data is displayed into multiple evaluation lengths. From each evaluation length standard defined characteristics are calculated (e.g. mean profile depth (MPD),  estimated texture depth (ETD)). Any evaluation length (profile depth as function of the distance) and its corresponding spectrum are also displayed. The spectrum and the characteristiscs of the evaluation length are recalculated real-time when spikes, that are considered to be measurements errors, are removed manually.
  5. Results, where you can export the results to a comma separated values file (CSV-file).

Texture Inspector will be sold as part of FLaSH or separately as of May 2015. Please contact us for more information.
