Asphalt with graphene has begun to be laid on the roads, which will double the durability of the pavement

New technologies in road repair using an asphalt-graphene mixture began to be used in England. According to manufacturers’ estimates, graphene additives will increase the average life of the road surface from six to seven to 12-14 years.

Since the discovery of this «magic» material, wherever they tried to attach graphene:

The innovative technology is being tested right now. From 19 September to 1 November, graphene will be added to the asphalt to be recycled on site during the renovation of a section of Britain’s longest A1 (M1) London – Edinburgh highway. The experiment will be carried out on a northerly carriageway between Newton on the Moor and West Cawledge, south of Alnwick.

The old asphalt will be stripped off, recycled on site, and a small amount of graphene, carbon in the form of films only one atom thick, will be added to it. Such material should be significantly stronger than conventional road surfaces. Laboratory tests have shown that the average life of the road surface will increase from six to seven to 12-14 years.

Potentially, the use of promising material can reduce the frequency of necessary road repairs. And this, therefore, will lead to a decrease in the cost of their maintenance. The results of the experiment will show how much the technology has justified itself, but they will have to wait several years.

This is not the first time graphene has been used in building materials and road surfaces. For example, British road workers are already successfully using GiPave, an asphalt mixture with the addition of plastic and this form of carbon. The difference is that graphene is introduced into a new material, not recycled material.

As we wrote earlier, the automotive industry is also not shy about promising developments using graphene. It is planned to introduce it not only into the batteries themselves, but also to cool the batteries — the thinnest films of this material have learned to be made quite cheap without losing a significant part of thermal conductivity. Such a system could become much simpler and preferable to the liquid cooling that is widely used today.
