I would have thought you got the world files from Cawster, which had the textures in the download when I just dl Appaloosa Plains. If I were you I'd download them from Cawster instead of going through the hassle of exporting them and hoping you have them all.
(Let me see if I'm on the same page- you want the roads that are in the world but are not showing right when you use the Road Tool to place them on the world map?)
What I'm saying is- I checked the roads in Appaloosa Plains CAW files and they don't show right when placing, as I thought you said. You'll have to click on the road you want to use and choose edit (in the road tool panel). Like you're making a new road but you're editing the roads already there.
Let me get on my desktop and get some pictures.
*Once you reset the roads in the Road Tool panel, it will reset all the roads on the map which are under that name (these are not default roads) and any new ones you place.
.................
Remember- once you edit the roads that the map uses, it will change all the roads under that name:
To edit them-
