VIDEO – let’s hit the “road of the future” thanks to smart coatings?

New types of coatings can reduce noise or heat on the roads.

A revolution is underway on French roads thanks to smart coatings. Reduce heat, reduce noise in the city center or even capture natural light … These are the benefits of new types of coatings.

Many municipalities are interested in this innovation. Heat and noise are two nuisances that the city of Paris seeks to mitigate. Thus experimentations take place in some streets of the capital. Thanks to these new coatings, the expected gain in three years is -2 degrees in heat, and -3 decibels.

In Montauban, several roads were covered with a soundproofing asphalt to limit noise. “It’s a duller sound, you always hear the sound of engines and two-wheelers, but it relieves,” witnesses a resident.

Innovative signage

But the road of the future can also be conceived around an innovative signage. “If we observe at nature, there are fish that emit light, we have been able to control this property, the pigments used in our painting catch the light during the day and restore it at night”, explains Jean-François Létard, the president of OliKrom, a company specialized in smart pigments.

In Pessac, a bicycle path has been covered with this white paint which becomes phosphorescent when night falls. A world first that is able to offer 12 hours of light and visibility beyond car headlights.
