Tarmac grading & tyre compound

[Zootopian]

Is there a list or common knowledge associated with the grading or type of tarmac that circuits have on the F1 calendars? i.e.

* The type of tarmac laid.
* The abrasiveness of the circuit.

Ultimately any circuit will chew up tyres if you drive over the limit though certain circuits must be known to teams & Bridgestone based on the type of tarmac to be either easier or harder on tyres.

If such data exists, it is not for public consumption.

Expensive data to gather, which pretty much means that it won't be shared publically. And probably not with the teams to be honest.

Also it's not just tarmac texture - the layout of the corners has a massive impact as well.
