To date, the instability, as well as the strength of laterite soils in the construction application, has been widely addressed by many scholars. One of the main strategies to improve the laterite soil's characteristics is to utilise an effective soil stabiliser (i.e., chemical stabilisation). Previous studies have shown that the strength of the …

Fig. 12 (a) illustrates the desalination process through bioremediation technique, in which compost consisting of salt-tolerant bacteria is added in the saline soil. In this process, the bacteria utilize the salt as food, and reduces the salt concentration in the soil. Desalination can also be done by employing the phytoremediation technique.

This technique is called lime stabilization and involves adding lime to the soil. The varieties of lime that are used to treat soil include dolomite lime, calcite quick lime, monohydrated dolomite lime, and hydrated high calcium lime. Soil stabilization can normally be achieved by using approximately 5% to 10% lime.

For black cotton soil stabilisation, different amounts of BA were added to the soil, and as a result, the optimum value was found to be 6% replacement of bagasse Ash. The best stabilization was obtained at this value, as MDD increased by 5.8%, CBR increased by 41.52% and UCS increased by 43.58% (Kharade et al. 2014 ).
