" When did super-elevation come into common usage? "
The information I posted came from the 1903 edition of "The Mechanics' HANDBOOK ", so it was in use then. The original copyright was 1893, but I can't be sure the information was included in the first publication.

The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!
