Two Common Compaction Mistakes, and How to Avoid Them are discussed in the Complete Guide to crushed.
The professionals who use them consistently will tell you that there is a certain kind of skill and understanding required for efficiency and quality.
Undertrained or careless work can result in two very common outcomes.Both will affect the effectiveness of the area beingcompacted.
To better prepare for compaction jobs, this will help those new to it.
Clays and silts are hard to break up once dried.They bind in a way that keeps the consistency of the soil.
The soil is mostly gravels and sand.The soil has no cohesive strength and can't be molded together when wet.It is more difficult to compact because of this.

You can tell by the machine's response.It can be a sign that the soil is too dense.
The compactors come with a rating.A common trick used in the industry is to take the max depth rating and divide it by 3.If this number is larger than the layer of soil being placed, you run the risk of over compacting.The 1” rule is a simple method for compacting base material.
If you don't have a large enough piece of equipment to handle a job, you can end up with under-compaction.
If the amount of lift or depth of soil is not correct, the impact of the equipment will travel less and the energy from the compaction will be returned to the piece of equipment.Too much depth and too much soil can be problematic.
Uneven settlement is caused by under-compaction.The weight of the structure can not be effectively absorbed by the soil.Structural issues can be caused by uneven settlement.
