Work Description:
The project consisted of stripping off the existing traffic paint and shotblasting the bridge deck to remove all contaminants and
roughen the surface. After the bridge deck was blown clean, a lightweight, flexible, high elongation epoxy-based overlay was
installed. An approved aggregate was mechanically broadcast into the epoxy to provide a highly skid-resistant surface.
Mechanical metering, mixing and distribution equipment was used to accurately blend and dispense the epoxy material with precision and speed in order to reduce installation time and minimize traffic disruptions.
Epoxy overlay systems are designed to protect a concrete bridge deck surface from the devastating effects of deicing salts. They have become an attractive alternative to latex modified concrete which lacks flexibility and adds dead weight.
