Wallace Craig, an Asphalt Association District Engineer in the Chicago office, prepared a handbook for his personal use on the proper use of asphalt which later was used as a model for the first Asphalt Handbook.
Many important industry groups were formed during this time due to the expansive need for road improvements including:
- the Highway Research Board
- the American Road and Transportation Builders Association
- the American Association of State Highway Officials
to name a few.
