The slope of permanent fill embankments should be no steeper than 2- lI4H:1V. Upon completion, the sloping face of permanent fill embankments shoul.d be thorougl�ly compacted to a non-yielding state vsrith a hoe-pack. The abov� recommended cut and f ll slopes are under the assumption that groundwater seepage would not be encountered during construction. If groundr�vater is encountered, the construction work should be immediately halted and the slope stability re-evaluated. The slopes may have to be flattened and other measures taken to stabilize the slopes. �, �,.,;,�� ;,�t n�r�,.3TA� t�, fln�,� �,n�ontroll�d over cut and fill slopes.

STRUCTURAL FILL Structural fill is the fill that supports structural or traffic 1oad. Structural fill should cc�nsist of c:lean gra.nular soils free of organic, debris and other deleterious substances and with pari:icles not larger than three inches. Structural fill should have a moisture content within one percent of its optunwn moisture content at the time of placement. The optimu�n moisture content is the water content in the soils that enable the soils to be compacted to the highest dry density for a given compaction effort. Onsite clean soils meeting the above requireinents may be used as structural fill. Imported material to be used as st�ctural fill shauld be clean, free-draining, granular soils containing z�o more LILT & t�SSOCIATES, INC.
