After the SBS modifier is added, the low-temperature performance of the asphalt material is obviously improved, the asphalt still has flexibility below a brittle point, after the SBS is used as a polymer modifier, stress concentration can occur around particles under the action of external load due to the difference of moduli of a polymer dispersed phase and an asphalt matrix phase after the asphalt is modified, a large number of micro striations are initiated, the development of the striations is stopped and hindered by another polymer particle, and when the striations meet, turning or branching can occur, and the deformation needs to absorb energy, so that the asphalt can show toughness after the polymer is added, and the low-temperature performance is obviously improved.
