New graphene-added asphalt to double road lifespan

It is generally accepted that graphene is used mainly in electronic devices, but the range of its unique properties is far from being exhausted by this. Italian companies Directa Plus and Interchimica have jointly developed a unique road surface - Eco Pave, combining asphalt with graphene.

Thanks to the graphene additive, the thermal conductivity of asphalt has improved - now it does not soften in the heat and does not crack in severe frosts. As a result, the service life of the road surface has doubled on average from 6-7 to 12-14 years.

Graphene-added asphalt is sure to be of interest to road construction and repair companies. In addition, after the roadbed gradually becomes unusable, it can be reused - dismantled, crushed, mixed with "fresh" asphalt and thus the waste problem can be solved.

Developers have now moved from laboratory testing to practical testing on small sections of motorways. If it turns out to be successful, it will be possible to talk about serial production of a new road surface.
