3Epoxy 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.
4Pavement Sealing
Decreased Corrosion Less Chemical
Infiltration Armored Pavement Surface
5What 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.
6Anti-Icing Can
Eliminate Frost Development Limit Black Ice
Development Minimize Snow Bonding
7Anti-Icing is Optimized by
Pavement Condition Forecasting Chemical
Types Pavement Interaction
8Anti-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.

- Friction tests by FAA
- Natural Snow
- Water misting
14Chemical Held on Surface ACY
15Durability
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.)
