Winter roads finished

I've just completed a large batch of roads, Once again I've used acrylic sheets as the base. This time the thin version that can be used in printers and photocopiers. After a quick spray of white primer it was quite willing to bond with a first coat of PVA sprinkled with sand. Then extra PVA added down the edges and centre with a more normal sand/grit mix. Then is was just the grind of applying the normal finishing touches

A quick idea of how the roads will look like in action
