Because they require so little, infrequent, maintenance it makes very little sense to pave asphalt roads to wind tower locations.

For the vast majority of wind farms, dirt or gravel roads connect masts to pre-existing infrastructure.

The largest wind farm in the US is the Alta Wind Energy Center: https://maps.app.goo.gl/rPjUGSTN979dfUoDA

The largest wind farm in Europe is the Markbygden Wind Farm: https://maps.app.goo.gl/ETVeMXpf1uPieTct8

Dirt and gravel roads.

I'm not saying that there have never been roads paved to create wind farms.

I am saying that the number of roads that have paved is so small that it is irrelevant.
