Measurement of grip (SKM) on federal motorways for data collection on concrete road surfaces / recording of grip

In order to create a statistically reliable database, a special data collection has been carried out since 2017 on various types of concrete road surfaces in the entire motorway network, which should serve as a basis for an integral consideration and the preparation of new concepts.

o Detection of grip in the right roll lane with TP Griff-StB (SKM) edition 2007/CEN TS 15901-8 (double measurement)

o Evaluation and data transfer:

,

Calculation of μSKM values (20 m and 100 mValues) according to TP Griff-StB (SKM) Edition 2007/CEN TS 15901-8

. Detailed measurement protocol of the respective measurement in the form of a test report

. Prompt transfer of measurement results using the access to the BSCW server set up by the BASt. It should be noted that, for example, individual values and raw data must be transferred to the BASt for further use at the same time as the measurement protocol.

. in digital form (PDF)

. as an Excel file with the raw data of the measurement and the 20 m and 100 m values

. Transfer of the data belonging to the measurement (raw data) including geodata additionally in GeoJSON format (geodata must be displayed in the coordinate system ETRS89 UTM32N (EPSG: 25832) (according to TR BGeoRG §3(4) in conjunction with BGeoRG)

. Entry in a continuously maintained overview of all measurement sections measured in the project and section-related mean values (SKM, MPD) in table format (Excel)
