Abstract

Literature published TerraZyme stabilization case studies are analyzed rationally for evaluating the performance of TerraZyme as a stabilizer. As a measure of the degree of stabilization, the percentage variation in soil index and engineering properties induced by enzyme treatment for various soil types are investigated. The literature shows inconsistent enzyme stabilization results. The causes of the inconsistency in test results and factors affecting the effectivity of enzyme stabilization are elaborated. The effect of soil characteristics on the efficacy of enzyme stabilization is analyzed. The results of enzyme treatment on soil properties such as Atterberg limits and indices, optimum moisture content, maximum dry density, unconfined compressive strength and California bearing ratio, for various soil groups with different enzyme doses and conditions of curing are also studied. An attempt has been made to quantify the attribute variation of treated soils, establishing, the underlying reasons, for the effectivity of enzyme stabilization and its performance within and among various soil groups. The effect of enzymatic treatment on each soil group is also classified. The research emphasizes the necessity of an elaborate organized study on the enzyme and soil characterization, to have a better knowhow of the effectiveness of enzymatic stabilization.
