Abstract: 
The paper presents the enzymatic stabilizers effect on grounds in the compaction process by vibration. It has been intended, by specific rheological modeling of the ground mixtures with organic additives, as well as by laboratory or "in situ" tests, to highlight the increased effect of elasticity longitudinal modulus and volumetric elasticity. Also, based on experiments it was determined the rheological evolution of the bulk modulus in relation to time up to the asymptotic stabilization specific to the final parametric values of the structure resistance and stability. The analytic assessment performed by modeling, as well as the experimental results significantly highlight the enzyme stabilizer effect. Thus, it is distinguished that by the pore size and the enzyme content modification, as a result of the recycled ground dynamic behavior, the Poisson's ratio increases considerably, reaching the value of 0.485. The experimental results confirm the possibility to increase the resistance and stability of ground road structures stabilized with enzymes. In this context, the compaction process by vibrations has to be performed in the optimal dynamic regime for the substantial modification of the material porosity.
