Trackless Tack-coat Systems for Canada:
Are We There Yet?
Year in review
What makes a good tack?
Demand for tack in western Canada
Tack Coats -Year in Review
Products we used last year:
What makes a good tack emulsion?
Provides a Bond
Wets Surface -
Less Tacky -
Three types of surfaces:
Need hard asphalt binder
No refineries in western
Canada make it!
Materials - Can we source?
Can we manufacture hard asphalt?
Suitable for all substrates?
Sense of Urgency
Blacklidge - USA
Have had a patented system in place for several years
McAsphalt - Canada
Starting trials 2014
Collaboration with CST
Sent samples to CST
Lab manufacture of hard asphalt
Lab and construction performance
Study -Two Phases
Phase One Results
Manufactured hard asphalts
Found correlations between asphalt and modifiers
Achieving 40-50 Pen
Emulsified hard asphalts
Six potential engineered designs
AkzoNobel "Tackiness Test"
Phase One Improvements
Increase the dosages of emulsifier to make more stable
Using co-surfactants – two emulsifiers
Alternative modifiers to harden asphalt
Components to making a good trackless tack
Western Can. tack demand and challenges
CST Study - Early successes
Future - Formulation, lab, and field work
Are we there yet? Almost.
