What are the different types of soil stabilization?

There are 3 main methods for soil stabilisation:

  • Mechanical stabilisation. This category consists of physical processes such as compacting or tamping with machineries including rollers or rammers.
  • Chemical Stabilisation.
  • Polymer Stabilisation.

Which chemical is used for stabilization of soil?

The chemical stabilization of soils is a relatively broad term that is used when chemical reagents such as quicklime, Calciment Lime Kiln Dust (LKD), cement, Bitumen, or other industrial co-products and bi-products are used to increase the strength of subgrade soil.

What are the types of soil bitumen?

Depending upon the above actions and the nature of soils, bitumen stabilization is classified in following four types:

  • Sand bitumen stabilization.
  • Soil Bitumen stabilization.
  • Water proofed mechanical stabilization, and.
  • Oiled earth.

What is the difference between quicklime and hydrated lime?

The key difference between quicklime and hydrated lime is that the quicklime (or burnt lime) contains calcium oxide whereas the hydrated lime (slaked lime) contains calcium hydroxide. The major source for both quicklime and hydrated lime is the limestone. Therefore, like limestone, these compounds are also alkaline.

Which method gives good stabilization?

The methods are: 1. Lime-Pozzolana Stabilization 2. Cement Stabilization 3. Soil-Bituminous Stabilization 4.

How is lime used for soil stabilization?

Method of Mixing Lime into Soil

  1. The soil which needs stabilization is scarified and pulverized by suitable equipment.
  2. Now add some amount of lime to the pulverized soil either in powder form or in the form of slurry and mix using suitable equipment.
  3. If lime powder is used, water should be sprayed allover the soil.
