With changing pace and time, considering the climatic and environmental impact, we have been continuously innovating. This is our mission behind introducing and promoting TerraZyme, an eco-friendly product. We at Manibhadra Earthmovers in association with Avijeet Agencies (P) Ltd (distributors of TerraZyme in India for past 19 years) have taken up exclusive rights for Western India Region for TerraZyme. This product is manufactured by Nature Plus Inc, USA. The vast experience of 30 years in road work of Manibhadra Earthmovers and their expertise has lead has lead to this synergy of interests in promoting TerraZyme.

TerraZyme is an excellent replacement for GSB and WMM. The use of TerraZyme leads to a saving upto10% to 30% - per Sq.mt in road construction. TerraZyme is a biodegradable product made from plant and vegetable extracts. It helps in the workability of soil by improving the engineering properties of the soil like CBR value, ITS, Density. It also helps in reducing OMC, plasticity index of soil and its permeability.

CALCULATION

Poisson’s Ratio varied from 0.5 to 0.4E value for each layer was taken from the above table.Loading – single axle single tyre

KENPAVE ANALYSIS

From the above Tables it can be observed that, the vertical stress at centre line of loading is 560 KPa (at vertical coordinate of 0). When the depth of the

pavement increases the stress reduces and it become 28.399 KPa at the point just above the subgrade. This stress level has to be kept as the bench mark.

When the conventional layers are replaced by the enzyme stabilized soil the stress levels have to be lesser than that of the standard cases. Trial and error

method was adopted to find out the minimum thickness of the stabilized material. Similar observation can be made in terms of vertical displacement.
