The Materials Bulletin list is maintained and updated as needed when it becomes necessary to modify acceptable materials on ADOT projects due to regulatory changes (i.e. FHWA mandates, Industry procedural shift, judicial rulings, etc.) and/or material replicability/availability. Below are the most recent changes to usable materials on ADOT roadway and bridge works.
These changes are effective retroactively to the date within each individual bulletin.
- Materials Bulletin 21-01: Use of Type 2 Glass Beads During Shortages On ADOT Projects (Effective 14 September, 2021)
