> The paint changes colour at temperatures below +4 degrees. According to Brestavtodor, this is a signal for drivers to slow down before the bridge. The paint still needs to be certified before it can be widely used.

On the R16 highway in Brest district, road markings that change colour when the temperature falls below four degrees are being tested. The trial section is on the approach to the village of Tsiukhinichy.

A snowflake pictogram has been painted on the carriageway before the climb onto a bridge. According to the republican unitary enterprise Brestavtodor, it was applied on the R16 road ahead of the bridge. The white snowflake turns pink when the temperature drops.

According to Brestavtodor, the inner part of the snowflake is made of a special paint that changes colour as the temperature falls. At temperatures above plus 4 degrees, the snowflake is white.

The pink colour, Brestavtodor explains, is a signal that ice may form on engineered structures: concrete freezes through faster. In that case drivers should reduce speed and be more alert.

The enterprise clarifies that the colour change indicates a risk of ice forming, not that ice has already appeared.

In the near future a road sign will be installed on the approaches to the bridge to inform road users about the experiment.

According to Brestavtodor, the experiment has been agreed with the traffic police (GAI) department of the Brest Regional Executive Committee's police directorate. Over the course of the winter, specialists will watch how the snowflake behaves and whether any inaccuracies arise.

According to Brestavtodor, the paint is innovative and goes beyond the current Belarusian state standard (STB), so it must be certified before it can be widely used on roads.

In future, such paint could be used for markings near bridges and overpasses.

According to specialists, no similar experiments have been carried out in Belarus before. The paint is made by a resident of the Brest free economic zone.
