Soil stabilizers and road recyclers are engineering vehicles that were once similar machines; however, they are now specialized road building machines and have developed into various machines.
Soil stabilization usually has the main objective of changing the technical properties of the soil itself, such as compressibility, bearing capacity, ease of work, permeability, sensitivity to changing moisture content, and development potential.
To achieve this goal, this stabilization process can be carried out in the simplest way such as compaction, using more effective techniques and also requires a large amount of funds, namely by mixing the soil with sand or cement, grouting or cement injection, fly ash, heating and so on.
What is the importance of Soil Stabilization?
The construction process in the form of road pavement is one form of land stabilization that is commonly practiced in society. This work aims to repair the material on local roads by using mechanical stabilization methods or adding additional material to the soil.
Soil stabilizers is also indispensable at project sites. Because the heavy equipment working in the project certainly requires a work foundation and roads that are strong enough and qualify as a foundation. So, the implementation of work in the project can be faster, more efficient and the results of work can be of higher quality.
One part of the soil stabilization process is to consider whether the soil conditions are sufficient to qualify as a construction site. If it does not meet the requirements, then the things that are needed include:
- Demolition of existing soil or material on site and replace it with a more suitable one.
- Improve the properties of the existing soil at the site so that it is better and meets the requirements for construction.
Soil Stabilization Method
There are 2 general ways that can be done to stabilize the soil, including:
1. Mechanical Stabilization
This method is done by mixing two or more kinds of soil with different gradations so that the material becomes better, stronger and meets the requirements. This method can also be done by dismantling the soil on site, then replacing it with materials that meet the requirements.
2. Stabilization with Additional Materials
This method is done by adding certain materials to the soil in order to meet the requirements. The material that is added is usually from the factory and mixed in precise proportions so as to improve the properties of the soil and make it stronger and meet the requirements.
The following is a form of proper and correct soil stabilization pre-mob inspection.
