As vantagens da utilização do método whitetopping na recuperação de pavimentos flexíveis deteriorados

Abstract

On the current scenario of ground transport in Brazil, where there is an increasing vehicles traffic volume, caused by the predominance of highways instead of railways, ally to the ease of automobiles acquisition, there is an ever increasing demand for maintenance of highways. The constant flow of vehicles on the roads brings up the challenge of performing maintenance on the highway with the least impact on traffic. Therefore, maintenance should be quick and sporadic. The high performance and minimal maintenance of the rigid pavement, when compared to the flexible, appears as a solution to these 2 frequent intervention needs. In this context, the concept of whitetopping emerges: a method of recovering flexible pavements with the use of concrete, in order to transform the old deteriorated asphalt pavement into a new concrete pavement. This article presents the advantages, in the economic, social and environmental spheres, of rigid pavement in comparison to the flexible pavement, emphasizing the feasibility of the use of concrete in the recovery of flexible pavements, known as the whitetopping method. It is a literature review based on specialized literature through consultation of books and scientific articles selected from searches. Due to the identified advantages, it is believed that it is a matter of time for whitetopping to consolidate itself in Brazil as a technology used in the rehabilitation of flexible pavements.
