The responses to this topic have offered many great options. After some investigation and suggestions from forum members, I ended up using a product mostly described as "Foamies." The product is basically a sheet of colored foam. The product is available in numerous colors, but I went with black. The product accepts a flat acrylic "pavement" color paint well. For stripping, I decided to use 1/8" auto pinstriping.
I approached the thickness choice in two ways. For North Main Street lined with MTH buildings, I used a 5mm with a 3mm over it to bring up the height of the road to bring the building curbing more in scale. For South Main Street at the opposite end of the table, I used 3mm for the road, and placed the Woodland Scenics structures on a 6mm "Foamie" sheet (12" x 12") to create the curbing effect. I painted the 6mm sheets a concrete gray...looks great bordering the flat black roads. The 5mm sheets l bought came in a 12" x 18" sheet; the 3mm sheets in 12" x 18"; and the 6mm sheets in 12" x 12."
I'll post pics of the new South Main Street area located below the mountain range, with two rivers running into Spring Lake, as soon as the finishing touches on the area are complete. The lake area may bring some likes
Here are the North Main Street pics first. Hope you all had an enjoyable summer...
