Aplicação de microrrevestimento asfáltico (com adição de polímero elastomérico) na revitalização de diversas vias urbanas no município de aparecida de Goiânia - Go

Abstract

The objective of the work is to present concepts of restoration and maintenance, especially of urban roads, specifications of services, in this case the service of resurfacing with asphaltic microcoating; aiming to increase traffic safety, driving comfort, service life of the coating and inhibition of pathologies in roads made of flexible pavements. In order to observe the application of the techniques, a case study was prepared in the municipality of Aparecida de Goiânia - Goiás. Data regarding the services were collected "in loco" and acquired at the Municipal Department of Infrastructure, collected through procedures guided by regulations in force in Brazil. The work addresses technical aspects that interfere in the quality of flexible pavements of the local road system that lead to the emergence of pathological manifestations. In order to parameterize the maintenance of streets and avenues, it was carried out as follows: In the first phase, pathological manifestations were identified in some roads, the probable causes and consequences on the pavement. In the second phase, the recovery method with asphalt microcoating with polymer addition is presented; seeking to improve safety and comfort conditions for users after adequate recovery. In the third phase, comparative results and conclusions are presented with quantitative and costs.
