ABSTRACT
In all civil engineering contracts soil is used as a construction material. Compaction of a soil is carried out to improve the soil properties and is a technique specified by the engineer. The most common examples are the sub-base of a road where the compaction may be in situ, or an embankment where the soil is brought in, frequently from a cutting being constructed elsewhere. Backfill after below ground construction is another example where soil may have to be compacted.
