Applicability of soil-enzyme for paving

Abstract

In recent years, there was a great offer of patented additives (enzymes) to the road market as solution to soil stabilization. This study aims to present a methodology to solve the problems that affects the use of additives in laboratory, because his use in conventional tests do not shown efficient for these purposes. For this, it was used a portable traffic simulator, easy handling and common in pavement laboratories. The soils used for the production of the tested tablets were lateritic soils from Rio de Janeiro-RJ, and the enzymatic products were imported. The study concludes, in principle, that the equipment used and the developed accessories are appropriate for this purpose and that the use of enzymes showed effective for some applications, but lacks more studies, including with the use of other types of soil to prove such effectiveness.
