Colección de firmas espectrales de los deterioros superficiales en estructuras de pavimento rígido en la Ciudad de Bogotá

Abstract

Pavement deterioration is an issue that affect mobility and figure it out how pavements damage is an engineering challenge. We present a spectral signature library of Portland Cement Concrete pavements distresses in Bogotá city. Nine different stages of pavement with a without distresses have been analyzed and six spectrum of each were measured. A spectroradiometer used is able to obtain spectra between 325 and 1075 nanometers. After spectra analysis of an individual distresses a spectral signature library of rigid pavement was made. Results showed that signatures highly represent pavement distresses and it can be used to classify hyperspectral images. Spectroradiometry is a good tool to evaluate pavement distresses because reduces time consumption compare with visual inspection that pavement engineers got used to doing.
