Marking film test on the A4: that's behind it

Marking foil test on the A4
Subscriptions & booklets

G The same road markings are commonly known from construction sites. They cancel the existing white markings without having to remove or cover them. While the white markings should remain on the road for as long as possible, the yellow markings must be removed after the construction site-related traffic management has ended.

Tests in Saxony and Thuringia

This residue-free removal of yellow marking foils Concrete and asphalt pavements often prove to be difficult in practice. Remnants of film on the road surface can irritate road users or make it necessary to mill the residues, which can result in damage to the road surface The traffic-related properties of yellow marking foils under real traffic loads will be researched on two test routes on the motorway. These are the A4 motorway between the Stadtroda and Jena-Zentrum junction on the Frankfurt am Main lane and the A4 between the Hermsdorf-Ost and Rüdersdorf junction on the Dresden lane.

Cross and longitudinal strips confuse motorists

In each of the test fields with a maximum length of 200 meters, yellow marking foils from three foil manufacturers were applied to the right-hand lane (load lane) in the longitudinal and transverse directions of the road. The vehicles that roll across the test fields are counted. In addition to removability, traffic-related properties such as grip, daytime visibility, nighttime visibility on dry and moist marking surfaces should also be measured and evaluated. The test should run for around 100 days.

Signs on the roadside provide information about the test fields. No speed limits were imposed. Nevertheless, drivers are always confused about the lane markings. As the Bild-Zeitung reports, there are always emergency braking and evasive maneuvers. However, there have not been any accidents so far.
