• Abstract:
  Chloride laden ice and snow thrown from plows can adhere to bridge piers. Eventually the chlorides migrate into the concrete and cause corrosion. This report looks at two methods of protecting bridge piers. One is a polyethylene shield and the other is a polyaspartic coating. The polyethylene shields were easy to install and could be removed for inspection. An attempt was made to use specimens to measure chloride contents and corrosion on protected and unprotected columns. However, mild winters and possible contamination of the specimens provided inconclusive results. The polyaspartics have potential to protect columns better than the epoxy-urethane currently used but require proper surface preparation.
