Epoxy Overlay Systems
Epoxy / aggregate overlays are being installed
across the country as a means to seal bridge
decks and apply wear coats. Many bridges in
Michigan have already been sealed.

What is Anti-Icing?

• Anti-Icing practice is an attempt to armor the
  pavement surface prior to a freezing or frozen
  precipitation event by use of freezing point
  depressants.

Anti-Icing Can
Eliminate Frost Development Limit Black Ice
Development Minimize Snow Bonding

Anti-Icing is Optimized by
Pavement Condition Forecasting Chemical
Types Pavement Interaction

Anti-Icing Smart Pavements

• Anti-Icing Smart Pavements are an epoxy overlay
  system that greatly enhances the residual effect
  properties of the pavement. These overlays are
  also excellent seal coats for the pavement
  surface and structure.

Durability
Epoxies have been and are presently being tested
in many states and in many different pavement
scenarios. Aggregates used to date are MI DOT
certified using MTM 111 (Determination of
aggregate wear index.)
