Stabilisation of soil improves the quality of sub-grade materials for recycling and re-use, thereby reducing the need for imported materials.
Stabilised site won material may be used to replace an equivalent imported crush rock layer.
The high production rates of stabilisation improves construction expediency.
Lime stabilisation reduces the shrinkage rate of a high plastic clay to less than 10% and raises the bearing capacity, for example: using 3% quicklime, a CBR 5% can be raised to 25%.
Mechanical mixing and compaction of extremely weathered rock improves permeability by reducing the scope for seepage through lenses, fissures and other faults.
Quicklime is the industry standard for field application of lime stabilisation. Hydrated Lime and other forms of lime exist but are less effective in the field.
Environmental benefits include reduced quantities of quarry products, export to tip sites and less traffic loading on the surrounding road network.
Quicklime Stabilisation permeability improves the physical and chemical properties of clay resulting in strength gains and reduced expansion. Treatment of the non expansive material with cementitious binders will further increase strength.
