Frozen soil is not acceptable. Fill Placement and Compac00n: Embankment fill should be p /aced in min honzonta/%fRs (6 to 12 inches loose lhirknes ). The fill should be moisture conditioned to within 2 percent ofopfimum moisture content and compacted to at /east g5 percent of standard pmclor maximum dry density (AS77d D 696). pfacirg and spreading of fit/ materials should be started at the lowest pant ofthe embankment.
