Hyperion 3000 ft ir spectrometer

In our study, we used Fourier-transform infrared spectroscopy (FT-IR) to probe the complex chemical dynamics arising from the amalgamation of the base AP-5 asphalt binder with varying concentrations of shredded mask residue (SMR)—specifically at 3, 6, and 9 wt. %. Each blend, reflecting these distinct concentrations, was subjected to a rigorous examination. The analysis involved 32 scans with a resolution of 1 cm⁻¹, spanning a spectral range of 4000–650 cm⁻¹, facilitated by the state-of-the-art Hyperion (3000 FT-IR) Spectrometer (Bruker Optics, Ettlinger, Germany). The acquired spectra were diligently normalized, with absorbance values cataloged to pinpoint the specific functional group interactions between the asphalt and the SMR. These detailed spectral data, when juxtaposed against the control asphalt blend, served to elucidate any chemical shifts or alterations induced by using varying concentrations of the mask materials.

The FT-IR was recorded on a Hyperion 3000 FT-IR Spectrometer (Bruker Optics, Ettlinger, Germany) with a spectral resolution of 1 cm⁻¹, a wavenumber range between 4000 and 650 cm⁻¹, and an average of 30 scans per sample. The bituminous samples as well as DCG were examined using a thin disk of the sample mixed with KBr (i.e., potassium bromide). FT-IR was conducted to reveal the changes in the molecular components and structures of the base asphalt (AP-5 asphalt) after treatment with different doses of discarded chewing gum (e.g., 3, 6, and 9 wt% DCG).

A Hyperion (3000 FT-IR) spectrometer was used to record the FT-IR (Bruker Optics, Ettlinger, Germany) with a 1 cm⁻¹ spectral resolution, a wavenumber ranging between 4000 and 650 cm⁻¹, and scans per sample with an average of 30. A thin disc of the sample combined with KBr was employed to chemically characterize the waste lipstick (WLS) as well as the unmodified and WLS-modified asphalt samples. Prior to and after aging, the FT-IR scan was particularly performed to learn more about the impact of adding different levels of waste lipstick (e.g., 5, 10, and 15 wt.% WLS) on the chemical composition and chemical structure of neat base AP-5 asphalt.
