is widely considered the industry standard for best practices in asphalt construction. The most current version is the Third Edition (2020) Post: MS-22 — Construction of Quality Asphalt Pavements

  • Roller patterns: Breakdown, intermediate, and finish rolling. How many passes? At what frequencies?
  • Temperature windows: The starting compaction temperature (typically 280-300°F for conventional mixes) and the minimum temperature for finish rolling (around 185°F).
  • Roller types: Steel-wheel vibratory rollers, pneumatic tire rollers, and static steel rollers—when and where to use each.
  • Density testing: Using nuclear gauges or cores; the importance of achieving 92–96% of theoretical maximum density.

Key Takeaways:

Do not rely on memory or “how we’ve always done it.” Asphalt materials, equipment, and quality expectations evolve. The latest edition of MS-22 captures the collective knowledge of hundreds of pavement engineers and field personnel.

  • Aggregate stockpiling and moisture control.
  • Drum vs. batch plant operations.
  • Temperature monitoring of the binder and aggregate.
  • Avoiding degradation and segregation during silo storage.

5. Compaction (The Density Imperative)

MS-22 famously states that “density is directly related to durability.” The compaction section covers:
