roadway color
Posted by LVGuy on Tuesday, May 07, 2019 6:25 PM

I'm trying to find a reasonably correct color to paint asphalt roadways. I know they aren't black, but rather some shade of gray. Any ideas what might look appropriate for an asphalt road in Pennsylvania coal country?

The "shade" of the blacktop, as it weathers and fades, will also take on a bit of the color of the aggregate used in the mix.

I have no idea what color typical road gravel is in the part of PA. your modeling.

Try a Google search for that area, and look at images, to see what the roads look like, unless you live there, than you can go look!

Roads in that part of the world are rarely asphalt, but more often tar and chip. The actual chip is almost universally a medium gray and the areas of tire wear are jet black tar if they're well worn.

Two things I associate with summer is the smell of hot tar and the infinite little pings of fresh chip flying up off the road onto the car.

I try to avoid using materials I have to paint when modeling asphalt, as painted road surfaces tend to acquire chips and gouges that ruin the effect.

The asphalt here is dark gray tile grout (Mapei brand Pearl Gray).  It yields a reasonable aged asphalt color without paint, and it's the same color throughout so damage isn't obvious.  The finished surface take paint easily for weathering.  Other grout colors both lighter and darker can be used for different effects.

I would say the best way to get a color you like is to go and take a picture of the real road you want to model. If you don’t live near the place you model then look on google earth or try to find pictures on the internet. Then test paint colors until you get a color you like always referring to the pictures of the prototype.

Mr wp8thsub’s road looks pretty good too, you may want to try his method. When it comes to road, there are an infinite number of meathods and most get a very good result.

Have you considered photographed textures?

Free ones are available here  https://www.textures.com/  

This and other sites also have textures for sale

 

I tried to sell my two cents worth, but no one would give me a plug nickel for it.

I don't have a leg to stand on.

If you want to see right now, today, what they look like, type in a town in the Lehigh Valley into Google Maps and turn on satellite view.

Generally, somewhere between Reefer Gray and Grimy Black is going to be close.

In some spots, the stone used in the asphalt mixure is a sort of boxcar red, so the roads can get a bit of that shade to them as well. Usually secondary roads as opposed to highways.

And there should be potholes. As everyone from Pa. knows:

I agree with Rob.
 
A painted surface over time will acquire scratches and dings.  I use Arizona Rock and Mineral powders.  They have several different colors of road powders, I use their Asphalt 121-0 for my asphalt roads.  I pour the power on the prepared roadway then add Elmer’s white glue mixed to 1:8 with tap water until the powder is a muddy paste then spread it with a taping blade to form the road.
 
 
 
 
 
Those roads are over 20 years old and still looking good.
