For many years the outflow meter (Moore) in combination with the SRT pendulum test or the sand-patch method have been used to determine the macrotexture of pavement surfaces. Both methods require consumables (water or sand). At the same time, the measured data obtained by these methods are prone to operator errors due to the manual testing procedure.<\/p>\n
In contrast, the measurement device ELAtextur 3.0 is largely free of operator errors and operates more accurately and faster.<\/p>\n
The rotating laser sensor of the ELAtextur 3.0 scans the pavement with high resolution. The integrated Mini-PC with fast ARM processor controls the device. Its software determines the MPD value (Mean Profile Depth) in accordance with EN ISO 13473-1:2004 and ISO 13473-1:2019 based on a part-circle segment of the texture as well as the ETD value after every measurement and shows them on the display of the measurement device.<\/p>\n
Additionally, the measurement results can be transferred to an USB stick. The specially developed evaluation software provides a presentation of the measurement results in test protocols at the workstation.<\/p>\n
The calibration plate, integrated in the transportation case, allows the performance of calibration measurements at any time and thus enhances the measurement accuracy.<\/p>\n
During outdoor operation the integrated GPS receiver (or GNSS receiver\/ additional option) provides the necessary localization data of the measurement points. The ELAmobil facilitates and speeds up the measurement operation.<\/p>\n
For texture measurements on cores, we have developed our core adapter (\u00d8 150 mm\/ other sizes available upon request).<\/p>\n
For texture measurements on cores of testing systems according to Wehner\/ Schulze (\u00d8 225 mm) we recommend our special device ELApws.<\/p>\n<\/div>
