· Explain factor affecting soil compaction:-

The following  factors of soil compaction are as follow:-

1.   Moisture content:-

It has been seen by the laboratory experiment that as the water content is increased, compacted density goes on increasing till a maximum dry density is achieve which further addition of water, decreases the dendity.

2.   Type of compaction:-

The type of compaction is also affected the dry density because any soil shows good result with the particular type of compaction i.e. at the same moisture content soil has maximum dry density with a particular type of compaction.

3.   Amount of compaction:-

The effect of increasing the compactive energy, result in an increasing in the maximum dry density and decreasing in the optimum moisture content.

4.   Type of soil:-

The maximum dry density achieved corresponding to a given compactive energy largely depend upon the type of soil.

5.   Addition of admixture:-

A number of admixtures may be incorporated in the soil to modify its compaction properties. The most commonly used admixtures are – cement, lime and bitumen.
