- The strength of TerraZyme treated road base is
similar to a semi rigid pavement with high CBR values,
thereby giving the ability to reduce the thickness
of asphalt layers.
- *The rates are based on Schedule
of rates in Pondicherry for the year 1999-2000.
- The savings for an area of 5,000 sq.mt is
Rs. 2,63,000.00
