Estudo das avaliações estrutural e funcional em trecho experimental com cinzas volantes

Abstract

The knowledge of the general condition of the pavements allows interventions in their structures aiming at increasing their life cycle. This paper aims to analyze the structural and functional performance in an experimental stretch with the addition of coal ashes in its granular layers. The structural evaluation was through using the Falling Weight Deflectometer - FWD equipment and the functional evaluation was through a smartphone application denominated SmartIRI responsible for estimating the International Roughness Index - IRI. The results showed high deflection values and acceptable values of longitudinal roughness over a large part of the stretch, therefore, it was not possible to directly associate these characteristics obtained with the use of fly ash due to the short time between the execution of the asphalt coating and the collection of data, although, in a segment of the analyzed section in which it presented a reduction in the carrying capacity, high values of longitudinal roughness were obtained.
