Abstract:

In an earlier study under the contract grant number BDV25-977-06, two portable Fourier transform infrared spectrometer ; (FTIR) were evaluated for their ability to quickly detect and/or quantify the presence of polymer modifiers, including styrene ; butadiene styrene (SBS) polymer and/or ground tire rubber (GTR), in asphalt binder. This report summarizes a follow-up ; study that evaluates a third brand of portable FTIR device, the Agilent Handheld ExoScan 4300 FTIR Spectrometer, for ; identification and/or quantification of polymer modifiers in asphalt binder. ; The same binder samples used in the earlier study were tested with the Agilent Handheld ExoScan 4300 FTIR Spectrometer. ; The test data were analyzed and compared with the results from the other FTIR devices included in the earlier study. It was ; found that the Agilent Handheld ExoScan 4300 FTIR Spectrometer can capture absorbance spectra similar to those from ; other portable FTIR devices and can read absorbance spectrum from asphalt mixture samples. The variability in test data of ; the Agilent Handheld ExoScan 4300 FTIR Spectrometer, however, is higher than that of the TruDefender FTX FTIR ; spectrometer.
