Proposta de intervenção em pavimento para AL - 135 na cidade de Maravilha-AL

Abstract

Flexible/semi-rigid pavements have a lifespan of 10 years, exhibiting surface defects over time/traffic, necessitating intervention for renewal. In addition to compromising user comfort, defects in the road surface contribute to increased vehicle operational costs and contribute to an increase in accidents along the route. Thus, proposals for interventions and restorations are essential for road safety and comfort maintenance. Therefore, this work is a case study aimed at analyzing the general conditions of the pavement, diagnosing possible causes of defects, and proposing restoration solutions for the AL-135 pavement segment that connects the city of Maravilha to BR-316. This work will follow the Brazilian evaluation standards and solutions catalog defined by the National Department of Infrastructure and Transportation (DNIT), which, for pavement quality analysis, employs methods such as the Global Severity Index (IGG), Continuous Visual Survey (LVC), and Longitudinal Irregularity (IRI). The methodologies adopted in the study have proven to be effective in evaluating and identifying defects in the pavement. However, it is important to note that, despite these advancements, the research emphasized the need for structural assessments for greater precision in solutions and rehabilitation strategies. It is important to mention that an approximate numerical value N was used for dimensioning; therefore, it is essential to conduct a traffic study and geotechnical analysis for adaptation to real conditions.
