GTA 5 road texturing technique

Hello, I been trying to learn from GTA 5 so I can create optimized artwork. I am curious on the road texturing. It seems like they use one texture for the curb, one texture for the road, and a third for the sidewalk, tiling them individually as submesh materials. I don't get how they are doing street marks and other random potholes and things though. Are they decals? This would seems like it would be bad for performance having tons of decals all over.

Decals aren't very expensive, some of the detail might be vertex blended.

In GTA V I've noticed that they have decals everywhere. EVERYWHERE. In general having them all over and filling the whole-screen is generally a bad idea but they seem to get it working well for them.

I think they use both decals and roads that already have marks on them to be honest. Seems like a chore to decal a long stretch of road when you could have that stuff in the texture as well and then use decals for special cases.
