HI Charles,

Interesting idea, but can you still get Shellac. I think that was made out of bug stuff. Everything is so synthetic now.

Google info:

Shellac is a resin secreted by the female lac bug, on trees in the forests of India and Thailand. It is processed and sold as dry flakes (pictured) and dissolved in ethanol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish.

Has anyone experimented with sealing the roadbed to reduce expansion and contraction? Shellac might be satisfactory and inexpensive.
