Quantifying SBS Content in Modified Asphalt Using Fourier Transform Infrared Spectroscopy

Article Preview

Abstract:

Styrene-Butadiene-Styrene (SBS) has been widely used in the modified asphalt engineering around the world due to its excellent contribution to both high and low temperature performance of asphalt. The content of SBS plays a critical role in the performance of modified asphalt. Therefore, an accurate and effective method to quantify the SBS content in modified asphalt was proposed based on the Fourier-Transform Infrared (FTIR) spectroscopy method. Two Infrared (IR) indices were provided to quantify the content of SBS. In addition, the practicability and accuracy of this method was verified by testing the prepared sample in laboratory.
