Spectroradiometric Laboratory Measures on Asphalt Concrete: Preliminary Results

Abstract This paper presents the preliminary results of a project concerning the use of spectroradiometric measurements for the characterization of aggregates and asphalts mixtures commonly used for road paving. Radiometrical measurements, in the wavelength range between 350-2500nm, were performed on selected samples with different compositional characteristics; the relationships between spectral signatures and different bituminous mixtures samples were analyzed. The results suggest that spectroradiometrics analyses can be used to establish new efficient and fast road classification procedures to support activities of pavement management systems and interpretation of remote sensed images. © 2012 The Authors.
