> -5kg of carbon per m2
That machine that chews up the road and lays it back down, how many kg of carbon per m2 does it burn?
I think too you have to compare the lifetime pollution of a bitumen patch versus the point source pollution of grinding a road up in the open air and putting it back down. There's going to be a ratio of resurface vs patch that has a lower cost than using either strategy exclusively. Especially if you use their chemistry for patches, instead of resurfacing.
