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

3. 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

4. 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

5. 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.

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

36. 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

37. 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.
