  • DETECTION AND ANALYSIS METHOD FOR RAPID DELINEATION OF AGING STAGES OF STYRENE-BUTADIENE-STYRENE MODIFIED ASPHALT
    Publication number: 20250137925
    Abstract: The present disclosure provides a detection and analysis method for rapid delineation of aging stages of styrene-butadiene-styrene (SBS) modified asphalt, including the following steps: performing a Fourier transform infrared spectroscopy (FTIR) test on unaged SBS-modified asphalt samples to obtain a copolymer index of IB0/S0 and neat asphalt functional group indexes, including the SI0, IB, aI0, ARI0, and CI0; performing the FTIR test on the aged SBS-modified asphalt samples to obtain an actual index of IB/S, SI, IB, aI, ARI, and CI; and delineating three aging stages of SBS-modified asphalt, including a polymer swelling stage, a polymer degradation stage and a component imbalance stage according to changes of functional group indexes. According to the present disclosure, the actual aging stages of the SBS-modified asphalt can be determined rapidly and accurately, providing a reasonable basis for the decision on pavement maintenance timing and mode.
