ChemSoilBinder

CSBTM (ChemSoilBinderTM) is a polymer modified chemical soil stabilizer that contains residues of many basic chemicals in the compound which are harmonized through special processes during its manufacturing. This product is harmless to the environment as it does not contain any toxic ingredients that can give rise to any adverse environmental effects.

Depending on the type of soil encountered, 5 to 7% of CSBTM (as a percentage of dry soil weight) is mixed with the in-situ soil to produce the stabilized, hard bounded soil layer which is much more stronger and durable than the original untreated soil. Generally, within the allowable dosage an increase in amount of CSBTM added would produce a stronger product. The moisture content of the soil-stabiliser mixture affects the degree of densification achieved during compaction, and degree of hydration during curing period. These factors will determine the strength of final finished product. In general, the degree of uniformity of spreading and then mixing of CSBTM stabilizer with the soil is one of the prime factors for yielding high strength stabilized soil while moisture content that close to the optimum moisture content (OMC) value of the mixed product is complimentary. Adequate compaction is of course another important element for the production of satisfactory stabilized soil layer. Depending on the type of the soil to be treated at the site the grade/type of CSBTM formulated for the job may vary.

The role/function of CSB^TM stabilizer is to convert the original loose and unbound soil in existence into a firm, stable bound layer with considerably improved strength characteristics shown. In the field, this is achieved by spreading soil stabilizer, pulverizing, mixing and compacting in-place soil with CSB^TM stabilizer under optimum moisture condition to yield a hard, strong and durable base course layer exhibiting the following improved engineering characteristics:

Factors (1) & (2) above will confer new and better engineering properties to the original soil in terms of dimensional stability and greater strength capacity. The former is most useful in the case of a clayey soil; especially those expansive clays such as the black cotton soil.

The valid reasons to support the adoption of CSB^TM stabilized soil as the alternative method for the construction of pavement sub-layer are:

The CSBTM stabilization technique involves relatively simple construction procedure and thus will bring about significant time saving during the construction.

Making use of existing soil material is one of the key feature of CSMTM method of construction. Depending on a number of other factors (e.g. wastage management, types of soil etc.) this method may subjectively be a cost effective one. Furthermore, the fact of less dependence on quarry products following the adoption of this method signifies greater chance of preserving our natural rock resources and thus rightfully regarded as an environmentally friendlier method of construction than the conventional type of construction involving unbound crusher-run road base and sand subbase etc.
