Making a curved road texture in Photoshop?

I have a very simple road texture (200*200) like this:

I need to create a curved version of this texture that is double the size (400x400). Here is a picture to give you a basic idea of what I'm trying to do:

The problem is, I have no idea how to curve the lines and the road markings in such a way that they would form smooth curves that tile seamlessly with the original texture. I have tried using the warp tool (I have the lines and markings all as separate layers), but the results look horrible. I'm pretty sure there is a pretty simple solution to this, but I'm rather inexperienced with photoshop. I've been banging my head against a wall because of this for the last two hours, so any help would be greatly apprectiated. And yes, I have tried to google for tutorials, but haven't been able to find anything that would address this issue clearly.

I'm using Photoshop CC. I also have Illustrator but zero experience using it.
