Patologia em pavimentos flexíveis

Abstract

The bad executions of the pavements results in the increased of defects that cause insecurity and discomfort to travelers. In order to change this scenario, it is necessary to study further the main pathologies found in the pavements. The main goal of this article is to make an analysis of these more recurrent pathologies in flexible pavements. As methodology, the research of bibliographic review, exploratory and descriptive with qualitative approach was used. Pathologies such as exudation, wear and slipping have the main cause of occurrence problems with the bonding mass, exudation occurs due to high temperatures, since wear arises by weather actions and slippage comes by constructive failures and bonding paints. The slits and cracks result from the excess of loads on the surface of the asphalt. "Pans" and Holes are pathologies arising from these pathologies mentioned previously, where structural ruptures that advance layer by layer occur. Despite the geography provides for the emergence of pathologies, an increase in quality control in the execution of pavements, as well as preventive and corrective maintenance are able to keep asphalt pavements in adequate safety conditions for users to use.
