a. Introduction
Depending on haulage costs, fly ash and bottom ash
can be used for highway embankments provided optimum moisture is maintained
and adequate compaction is provided. The
source can come from an operating power plant or reclaimed ash can come from a
lagoon or stockpiled ash. The
product from an operating plant normally can be delivered with close
limitations on moisture content. Moisture
content of fly ash from a lagoon or from a stockpile can vary considerably depending on
its location within the lagoon or stockpile.
