Lime Stabilisation & Fill Drying - Process

Lime stabilization is a process used to improve the properties of soils or other materials by adding lime. The process involves the addition of quicklime or hydrated lime to a soil or other material, followed by mixing and compaction.

The first step in lime stabilization is to select the appropriate type and amount of lime to be added based on the characteristics of the soil or material being stabilized. Quicklime, also known as calcium oxide (CaO), is the more reactive form of lime and reacts with water to form hydrated lime or calcium hydroxide (Ca(OH)2). Hydrated lime is less reactive than Quicklime which is more commonly used for stabilization.

Once the appropriate lime and quantity has been selected, it is added to the soil or material to be stabilized. The lime is spread evenly over the surface of the soil, and then mixed in using a rotary tiller or other mechanical means. The lime reacts with the clay minerals in the soil, causing them to break down and release water, which makes the soil more workable.

After mixing, the soil and lime are compacted to the desired density using a Padfoot roller. The compaction process helps to improve the strength and stability of the soil, as well as reducing its susceptibility to erosion.

The final step in lime stabilization is curing, which allows the lime to fully react with the soil and develop its beneficial properties. The curing time varies depending on the type and amount of lime used, as well as the environmental conditions. Typically, curing takes several days to several weeks..
