Soils used for lls should not contain any vegetation or foreign material that would cause uneven settlement Fill and Back ll Cont a39 a Clearing and Grubbing should be completed before any ll operations are undertaken Sloped surfaces should be plowed or broken up to enhance mixing with ll material Filling and back lling should be placed in layers lifts of 8in loose thickness when machine compacted and 4 inches when hand compacted 23 Compacting Applies energy to the soil to consolidate it by compressing air voids to increase the soil s dry density Proper compacting Minimizes settling Increases loadbearing characteristics Increases soil stability and Reduces water penetration Purposely densifying or increasing the unit weight of a soil mass by compaction with rollers tampers of vibrators can improve its structural properties Help prevent differential settlement 213 7 Compacting Requirements Speci ed as a percentage of the maximum d densi of the soil in the test procedures D1
