Getting asphalt color right - Model Railroader Magazine

It has taken me many years of modeling to build my railroad and the scenery around it.  That's an important consideration going forward, as continued ease of construction for the next years is another consideration.   So, I use straight-from-the-store paints, so I can just pop out and get more when I run out.  I use thinned craft paint gray, applied as a wash, for roads and a slightly lighter gray spray for sidewalks.

Incidentally, for my city blocks I cut the sidewalks to fit around the buildings, so the buildings sit inside a slightly raised sidewalk, which eliminates light leakage at the base of illuminated buildings.
