Abstract

The objective of this research was to obtain International Roughness Index (IRI) for pavements on bridges using smartphones, equipped with accelerometers, enabling the acquisition of acceleration data and the determination of the irregularity by numerical procedures, consisting of double integration of vertical acceleration. Measurements were made on three bridges, by crossing vehicles, equipped with two mobile phones with 100 Hz acquisition rate. One of the devices was arranged inside the vehicle and another in the suspension system tray.  Rod and level approach was used to validate the proposal. The conclusions show a good convergence between the methods presented to obtain bridges surface profiles, showing good indication of the use of smartphones as a simple and economical alternative method, revealing easy operation and good productivity.
