210.01 Description
Compact the embankment and backfill materials by means of mechanical tampers or vibratory compactors. Use this method of compaction wherever materials cannot be adequately compacted by other approved methods.
210.02 Materials
Refer to Section 916.
210.03 Construction
After approval has been given by the Engineer, place approved material in horizontal layers not exceeding 6 in. loose depth over the entire area. Tamp and uniformly compact the material using mechanical tampers or vibratory compactors. Refer to 204.03.04 for moisture and compaction. When backfilling around abutments, retaining walls, culverts, utilities, or other structures, prevent any wedging action against the structure. When placing backfill against existing slopes, excavate benches or steps. Place the backfill in horizontal layers as described above and wide enough that there is a horizontal berm of thoroughly compacted material behind the structure at all times for a distance at least equal to the height of the structure remaining to be backfilled, except insofar as undisturbed material protrudes into this space. Tamping may be required over additional widths when the material cannot be adequately compacted by other methods. When installing structures below subgrade in embankments, place the tamped fill to a depth of 1 ft over the top of the structure. In excavation sections, extend the tamped fill to the surface of the finished earthwork.
210.04 Measurement and Payment
Compacting embankments and backfills by mechanical tampers or vibratory compactors will not be measured but the cost will be incidental to the pertinent items specified in the Contract Documents.
