• Abstract:

   In view of the BR-319 implementation scenario, with the execution of Lot Charlie and the contracting of projects in the middle section, and the introduction of the new national dimensioning method (MeDiNa), the present work sought to evaluate the influence of the behavior of the resilience module with the gain of ±2% of moisture in soils of BR-319. Soil characterization tests were carried out, such as Atterberg limits, granulometry by sedimentation, and real density, in addition to the resilience module according to the DNIT 134/2018 standard. As expected, the results showed that the moisture gain generated a reduction of more than 50% in the average resilience modulus. The confining stress-dependent model presented a low frame, and the deviation stress-dependent model showed a better frame, but the composite model used in MeDiNa proved to be the most suitable for this type of soil, regardless of moisture.
