Compaction:

compactor1Compaction is an absolute requirement in at least some part of most earthwork projects, and is usually worth its cost in filling and back-filling even if it is not required.

The primary effect of a piece of compaction equipment is usually to compress material under it by dead or static weight. There is also a kneading effect which is also desired.

A vibrating compactor shakes soil particles individually, causing a tendency to move into closer contact with each other. loose soil such as sand or clean gravel my be sufficiently compacted by vibration alone but usually it is desirable, and often essential to have weight on the vibrating surface.

many vibratory rollers are of an articulated construction, with engine and control section driving by means of a pair of large wheels which usually are rubber-tired.

vibrating rollers usually give best results when moving slowly. Vibration greatly increases roller effectiveness on loose, granular soils, but makes little difference on silt. The rule of thumb is “The larger the grain, the greater effect.

  1. Thank you for your insight on this matter, it was very helpful and thorough. I don’t think a lot of people know how many steps really go into the compaction process. It is vital to know exactly what kind of earth you are dealing with when compacting and this explains exactly why it is so important. Thank you for taking the time to write and share this article.
