AASHTO TP 128-17 method covers the measurement of the oxidation signal in an asphalt mixture by a portableinfrared spectrometer (PIRS) equipped with a diffuse reflectance accessory. Three oxidationsignals are compared: (1) the in-place pavement, (2) asphalt mixture production sample, and(3) the approved job mixture formula specimen. The oxidation signals are determined from aspecified peak value from the absorbance spectrum of the asphalt samples.
