I can’t say for sure but I doubt it. Brick is not as hard as stone. However, in the Carrizo Gorge I saw ballast composed of broken firebricks mixed with cinders.

I would be very surprised if it has not been somewhere. I doubt it is done very often. It would be difficult to tell by looking at the road. I doubt you could tell if the aggregate was cruched brick or red stone.

This is what a newly paved road looks like:

You can see it is nearly pure black. This will not last long.

This picture shows a strip of asphault six months old leading to the new pavement. The older section of the road is lighter gray and much older. Three colors af blacktop all within a few feet.

This is a close-up of the new pavement:

This is the older road:

You can see that the aggregate color is showing in the older road. This is even more obvious at the point where the sections adjoin:

Look at this crazy sidewalk. There is a fresh concrete section, old concrete, and pavers onn the side closest to the camera. This would look terrible on a model railroad scene.

Keven,
I believe the pavers are concrete that has had a mold pressed into it to make it look like pavers. It would be interesting to see what it looks like in a few years.
I thought of a good material to use as a road surface, a fine grit sand paper! With a coat of paint it would look pretty convincing IMO…
Color would also depend on the paving type. I don’t know the names but in one they put a layer of tar down and then spread what ever gravel they are using for the surface. later they come back and sweep the loose gravel up. You would have the color of the gravel from the start. This is the cheapest and doesn’t last near as long. The other is where the gravel and bitumen is mixed at a plant and transported to the construction site where it is laid and rolled. This is the method most used today. It last longer.
Other than brand new pavement that is uniformly black, any road with some age on it will show several colors from dark to light that will give it some visible texture. How do you replicate that texture (in any color)? I would think that lightly painting fine sandpaper with a thin wash then rubbing it when dry might give it some of that textured look. Anyone tried that?
