Smartphone, Texture, Wearing Course, Distress.Abstract
This paper analyzes surface conditions of an Asphaltic Concrete paved road, Surface Treatment and Cement-Concrete, and also an unpaved road, using a smartphone application called Roadroid. The considered characteristics of surface conditions are associated with texture and surface distress. The analysis is performed utilizing a comparative BoxPlot chart and a central trend measures. In relation 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 conditions analyzed by the smartphone app are similar to the surface conditions provided by road agencies and those segments with high variation 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.Downloads
