Steps

  1. Obtain the current AASHTO M249 standard through an AASHTO subscription or a state DOT's incorporated-by-reference copy — the full standard is not freely published.
  2. Request the thermoplastic manufacturer's certified test report showing binder content, glass bead content, and TiO2 pigment level against the spec's minimums.
  3. Confirm the state DOT's own specification manual, since many states incorporate M249 by reference with local modifications.
  4. Verify application temperature guidance against the manufacturer's data sheet rather than a generic rule of thumb.
  5. Document the certified test report in the job's material submittal.
