Thermoplastic road marking performing over time

13. January 2012

“Inadequate and poorly maintained signs and markings are often cited as the contributing factor to accidents. While only 25 percent of travel occurs at night, about 55 percent of the fatal accidents occur then.” FHWA (Federal Highway Administration, USA)

ViziSpot® and PREMARK® Vizibility at Test field Torfhaus


One way to reduce the number of fatal accidents is by improving the night time visibility of the road markings, and hence improves the retro reflection of road markings in order to be able to see them.

The thermoplastic road marking material ViziSpot is an example of a Type II road marking that performs and delivers night time visibility in both wet and dry conditions. After 5 winters at the Torfhaus test field in Germany with an average daily traffic load of 8000 vehicles, ViziSpot still reaches R4, RW2 and Q4 according to EN 1436. Also, the preformed thermoplastic PREMARK Vizibility applied as Type I marking performs at the Testfield in Torfhaus, and after 5 winters PREMARK Vizibility reaches R4, Q4 and S3.

Both markings show minor snowplough damages, although snowploughs with steel blades have passed over the test field 1484 over the 5 winters, and the test field has been salted 1899 times during the years.
