Graphene reinforced asphalt to combat potholes?

I wonder if these potholes filled with this wonder stuff would cause issues as the normal road surface around it crumbles as its not as strong , a bit like the potholes you get around speed bumps ?

The wonder stuff isn't for filling potholes. it's for resurfacing roads that are less likely to develop potholes. For the reasons you describe it would probably be daft to use it for repairs.

The problem is, it's a long term investment. You'd pay more up front but it would last longer and need less repair (in theory, if it doesn't dissolve after 2 years) leading to reduced lifetime costs. Let's face it, no one has spare cash to invest in the long term, when it will be someone else's problem by then anyway.

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.

I'm not sure what today's price would be but back in 2022 highways grade asphalt was £110 - £120 per square metre just for the material. Laying and rolling was extra. I only know that as I had to arrange to have a strip of the A46 resurfaced after the company I was working for had some road sensors and cables installed.

The problem we’ve got in this country with the roads, utilities, etc is the manager in charge has a budget for the job, he bodges the job with cost cutting measures and looks good for doing the job under budget. They get brownie points, promotion, bonuses etc shareholders profits go up and we get shite utilities.
Short term thinking maximises profits.

I wonder if this is a good place to recycle wind turbine blades....

Strip off the polyester / epoxy resin and chop up the glass fibre and mix into tarmac for added strength at little cost?
