Retroanálise e avaliação estrutural de um trecho de pavimento asfáltico da rua Bento Martins no município de Uruguaiana – RS

Abstract

The movement of vehicles on roads is a significant factor contributing to pavement damage over time. It is a common practice to evaluate these issues by studying the elastic and plastic deformations in the pavement layers. A non- destructive test was conducted to obtain deflectometric deformations using a Benkelman beam on Bento Martins Street, an urban area in Uruguaiana/RS. The renovated section underwent testing from the sub-base layer to the flexible asphalt coating layer. Data on deformations in 26 piles were collected. With the deflection bays of each pile, BackMeDiNa software was used to conduct a retro-analysis test and obtain resilience modulus values. In the sequence, the MeDiNa software dimensioned the pavement structure based on the obtained modulus values. The results provided information on the percentage of the crack area and wheel track sinking thickness. To evaluate the damage caused by traffic flow at the end of the project estimate and to validate the effectiveness of the paving endeavor.
