Effective Depth of Soil Compaction in Relation to Applied

Some studies have claim that modern dynamic compaction equipment are capable of properly compacting lift layers as thick as 6 ft (and even greater thicknesses – see Zou et al. 2005). For these reasons, the WisDOT would like to re-evaluate the 8-in lift embankment construction requirement and carefully develop energy and compaction efficiency data.

5+ FACTORS WHICH AFFECT FIELD COMPACTION OR DEGREE OF

3. Layer Thickness / Thickness of Lift. Degree of compaction is inversely proportional to the layer thickness, i.e. for a given compactive energy, thicker layer will be less compacted as compared to thin layer. The reason is, for thicker soil layer the energy input per unit weight is less.

For blacktop, it pays to lay gravel on thick

Install the crushed gravel in layers. The first layer should be 3 to 4 inches thick. It should be graded fairly smooth and then compacted with a heavy rolling machine. Once completed, install the second lift of gravel. The width of the gravel base is very important. It should extend 6 inches beyond the blacktop wherever possible.

Caterpillar Compaction Manual WORKING WITH NATURE

Again, the soil is compacted in three layers by 25 hammer blows in a 4 inch (102 mm) diameter mold. This test imparts a total of 12,400 ft. lbs. of compactive effort to the soil sample. Modified compaction tests also have been introduced by AASHTO in connection with structures requiring heavier bearing strength to support extremely heavy loads or to limit settlement.
