This paper analyzes the surface conditions of a paved highway paved with Hot Mix Asphalt Concrete in six traffic lanes, to a length of 4.1 km, using two applications for smartphones, called SmartIRI and RoadLab, which measure the longitudinal irregularity and express it through the International Roughness Index (IRI). The study demonstrated that the use of the applications could be a viable alternative to the traditional methods of evaluation of the functional quality of the Brazilian highways, due to having a low cost, easy operation and accuracy better than the subjective evaluations. The results identified that the applications provided different values for the longitudinal irregularity, possibly due to the calibration process of the models used. However, in the case of the qualitative classification, the applications provided similar parameters and, through the longitudinal irregularity, were able to identify the areas of the pavement that require maintenance by the road managers.
