Benefits arising from the use of RBI Grade 81 Soil Stabiliser

  • Elimination for the need to replace soil material
    RBI Grade 81 is able to stabilise all types of soil, whether very sandy or high clay content soils, thereby avoiding the otherwise necessary replacement of in-situ material. By avoiding a soil exchange program, and vastly reducing the need for aggregate, RBI Grade 81 lowers the cost profile of road construction significantly in comparison to conventional methods.
  • Productivity savings:
    Due to the avoided replacement soil program, use of RBI Grade 81 leads to significant savings in labour costs, contractor costs, engineering and equipment costs and the cost of general raw materials. The productivity of site is dramatically improved, allowing projects to be completed well ahead of schedule at lower cost. RBI Grade 81 creates project viability where it previously did not exist.
  • Long-term benefits:
    The use of RBI Grade 81 eliminates the requirement for on-going maintenance, regardless of prevailing weather conditions. Pavement layers designed to incorporate RBI Grade 81 exhibit extended life-expectancies by years.
Soil stabilisation savings

Environmental considerations

  • RBI Grade 81, in addition to reducing the depletion of natural resources, offers significant environmental benefits over conventional stabilisation methods. Documented in various 3rd party life-cycle analysis, RBI Grade 81 has been cited numerous times for its environmental burden reduction profile."

RBI Grade 81 profile pre, during and post construction

Pre Construction

  • RBI Grade 81 facilitates the use of in-situ soil material, avoiding the conventional need for sourcing quarry materials, extensive production and transportation of lime and stone material and the dumping of asphalt
  • Reduction in raw material requirements in terms of stabilisation materials, fuel, labour and construction time
  • Reduction in raw material requirements in terms of stabilisation materials, fuel, labour and construction time

Construction

  • Reduction in requirement for non-renewables in energy consumption and soil materials
  • Minimisation of energy consumption in the construction phase
  • Waste materials from steel works and coal fired power plants recycled as a component of RBI Grade 81
  • Complete elimination of waste dumping to landfill, RBI Grade 81 facilitates the use of recycled soil material
  • Significant carbon offset in savings achieved during road construction phase
  • Allows for the recycling of asphalt, stabilising the sub-layer of soil

Use of Road

  • Eliminates leaching of bitumen and harmful chemicals due to integrity of sub-layer treated with RBI Grade 81
  • Prevention of soil erosion
  • Minimisation of dustiness of gravel roads avoiding the contamination of vegetation of crops
