CONSTRUCTION OF FLY ASH ROADWAY EMBANKMENT IN ILLINOIS

Electrostatically precipitated fly ash is a readily available source of structural fill in many metropolitan areas of the Unted States. A site was chosen by the Illinois Division of Highways near a large power plant for both a trial embankment and a highway embankment constructed with fly ash. A methodology for construction of fly ash embankments was developed that included spreading fly ash in thin lifts, scarification, and compaction by a vibratory roller. A clay seal was used to aid in confining the fly ash during construction and to provide a means of supporting vegetation. The performance of this roadway embankment has been satisfactory in respect to both structural stability and aesthetics.
