Test Certificate regarding the suitability of the RetroTek-M mobile pavement retroreflectometer for measuring the coefficient of retroreflected luminance RL of the surfaces of road markings in wet conditions.

These tests were performed in a laboratory and on the road in December 2018 & January 2019

Brief:

Determination of the suitability of the RetroTek-M Mobile Pavement Retroreflectometer with 30m geometry (referred to below as “RetroTek-M”) for measuring the coefficient of retroreflected luminance RL of the surfaces of road markings, in a laboratory on wet samples, and on a road surface in wet conditions.

Comparison with measurements from a portable handheld measuring device:

Determine the accuracy of the RetroTek-M by comparing the RL measurements from the RetroTek-M with those obtained with the portable (handheld) retroreflectometer LTL-XL on a road marking test field.

 

Conclusion:

The measuring system “RetroTek-M” provides, within the scope of an acceptable measuring accuracy, the same measured values of the coefficient of retroreflected luminance RL as a portable, handheld measuring device when measuring wet road markings in laboratory and real road situations.
