Abstract:Blended calcium sulfate (BCS) is fl uorogypsum (FG), an industrial byproduct,
blended with lime or limestone. Approximately 90,000 metric tons (100,000
tons) of FG are generated annually in the United States, posing a serious
problem for environmental disposal. The LADOTD has been using BCS in
pavement construction for the last 15 years. While this material has performed
satisfactorily after construction, its moisture sensitivity has concerned LADOTD
engineers because of its construction diffi culty in wet environments.
