Estudo da condição de superfície em rodovias por meio do uso de aplicativo para smartphone

Abstract

This paper analyzes surface condi!ons of an Asphal!c Concrete paved road, Surface Treatment and Cement-Concrete, and also an unpaved road, using a smartphone appli-ca!on called Roadroid. The considered characteris!cs of surface condi!ons are associ-ated with texture and surface distress. The analysis is performed u!lizing a compara!ve BoxPlot chart and a central trend measures. In rela!on to the textures, it is verified that open macrotextures in wearing courses presents higher values of irregularity, even in the absence of distress. It is also observed that the surface condi!ons analyzed by the smartphone app are similar to the surface condi!ons provided by road agencies and those segments with high varia!on coefficient values, present a significant amount of distress, especially patches and potholes. With this analysis, it is expected to contribute with the most reliable data, obtained through the use of smartphones, in order to aid managing groups on decision-making.
