How was the paint on the roads in this pack done?

Signovinces

My friend bought this pack a while back and a few days ago i finally had the time to visit him and check it out as i'm learning modeling. Looking at the files in the pack i couldn't figure out how the author of this pack had made the paint on the roads for the pack as there were no files in the pack where the yellow/white paint was present. The yellow/white paint wasn't on the roads (but the road texture was) when i opened a fbx-file in 3ds max but in Unity there were paint on the roads.

Any ideas as to how "magic" such as this is done?

maybe a shader and a black and withe mask with yellow color

A little digging, and I found the answer. Nice method.

QT-Road: A special shader used for the roads with lines. The shader takes a diffuse texture, then takes the Red Channel, cranks up the contrast, and multiples vertex colors on top. The intended result is the appearance of worn, painted road lines. This shader is applied to all Road-Double objects.
...
All shaders were made in Strumpy Shader Editor. The source graph files are included for all but the Metaclouds.
