Graphene reinforced asphalt to combat potholes?

Costs an additional £2.50/sq metre

Essex Highways, the highways authority for Essex County Council, installed hot rolled asphalt enhanced with graphene, the strongest substance ever recorded, on part of the A1016 in Chelmsford in 2022.

Although more expensive than standard hot rolled asphalt, tests have shown it is more resistant to weather and traffic.

Incidentally, the guy interviewed is called Mr Goosey. I wonder if he has a daughter named Lucy?

It is perfectly possible to repair potholes properly with normal asphalt, as I pointed out recently.

It is now 17 years later. The repair was done so well that, for a change, the hole never reappeared.

Interesting. But saying it costs £2.50 more per sq meter doesn't mean much without the context of what proportion of the total that is, which they don't give.

If it normally costs £100 per sq meter, then an extra £2.50 is hardly anything, but if it normally costs £10, it is a big chunk extra. It is difficult to find costs, but I think it will be closer to the £100 than £10.

We made this fabulous stuff. It has to be useful for something..... well we can always use it on the roads.
