Promoting the use of Emulsions

Now that the AASHTO Standards exist for some Emulsion Treatments we need to:

  • 1. Devlop a marketing plan / marketing tools
  • 2. Promote the technology to
  • A. Agencies
  • B. Industry
  • C. Academia – create course curricula
  • 3. By whom and how will this be done – For discussion
  • A. Regional PP groups?
  • B. AASHTO SOMat, SOMaint, SOHwyDesign, Asset Management?
