Yep. I mean .. check it out. Now .. think about it. You want a road. Most that I have seen use some product applied to the layout .. mat-board .. plaster .. and then you do whatever is needed including additional coloring if needed, weathering … road surface markings. Think how much easier it would be if you transferred where you needed a road to some paper while on the layout .. and then take that to your workbench and create the road there. Not only will the flexible nature allow the road to fit the layout easily .. but think how much easier it would be to do all of that weathering, surface markings etc.
Remember. It doesn’t have to be cracked like the example here. If you didn’t use the air eraser or brush to widen the cracks you could easily represent a road in fairly good condition. The cracks would mostly close up.
