Abstract

Roads are vital for the economic growth of a country. Keeping balance between performance and cost of the roads and at the same time fulfilling the environmental regulations is becoming a challenge for public and private sector. Traditionally used soil stabilizers (lime, cement and bitumen) are becoming costly. Gravel and sand, which are introduced to alter the soil properties are depleting and becoming increasingly expansive. This scenario has led to an urgent need to identify and introduce new materials to improve the roads performance and to keep the cost at an affordable level. In this respect different types of stabilizers ranging from inorganic to organic have now been tried in laboratory and in field to evaluate their suitability as soil stabilizer. Recently bio-enzymes have emerged as a new chemical for soil stabilization. They are organic materials which are supplied as concentrated liquid. It is claimed by bio-enzymes manufacturers that their products are effective, environmental friendly (non-toxic), cost effective and convenient to use. They improve the compressive strength, reduce compaction effort and increase the density thus reducing the permeability as well. But the studies so far suggest that these claims must be verified through independent laboratory testing before applying these bio-enzymes in the field.
