Conventional Method of Road Construction The use of GSB – Solling, SGMIX, etc., The use of different graded blue metal – WBM, WMM.

Conventional Method of Road Problems High Cost due to decrease in the construction materials suitable for the road construction Low life cycle – Flexible pavement High Maintenance Cost Damages like rut, potholes, erosion, wash boarding Needs surface treatment

TerraZyme – A bio enzymatic soil stabiliser TerraZyme, manufactured by Nature Plus Inc – U.S is an excellent replacement for metalling and solling. TerraZyme is a liquid extract from sugar molasses that improves the engineering qualities of the soil like CBR values and density and decreases the OMC, plasticity index of soil. TerraZyme is manufactured by Nature Plus Inc, USA under ISO – 9002 certification

Benefits of using TerraZyme Cuts construction cost by 10%-40% Higher CBR value / higher road strength: TerraZyme base structures have a much higher CBR value. Lowers the maintenance cost by 30-50%. Saves construction time by 50% The life-cycle of TerraZyme treated roads increase by 200–300%. Pavement thickness is reduced by 30-50%, being semi rigid in nature. Environment friendly and bio-degradable product.

National Highway – 66 , Tamil Nadu A Case Study The Road presently caters to 1,300 commercial vehicles / day. Close up view of the Road.

Comparison between Conventional and TerraZyme treated road. TerraZyme treated road without Asphalt. Conventional road with Asphalt.

Economic Benefits of using TerraZyme The road construction was cheaper by 30% The road was used for one year with heavy traffic without any black topping. The use of TerraZyme gives the opportunity to the government agencies to plan diversion roads without any black topping

Conclusion Roads, constructed using TerraZyme are Cheaper The life cycle of structures built using TerraZyme is increased Maintenance cost are reduced due to higher strength and stiffness achieved by using TerraZyme. Structures are built in much quicker time using TerraZyme.
