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.

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.
Pavement Sealing
Decreased Corrosion
Less Chemical Infiltration
