Effect of Base Asphalt on Properties of High Content SBS Modified Asphalt
High-content SBS modified asphalt was prepared with 8 different base asphalt and subjected to thermal oxygen aging.The relationship between the composition and physical properties of base asphalt,ag-ing properties of high-content SBS modified asphalt was discussed.The results show that the high and low temperature performance of base asphalt is not related to the high and low temperature performance of high-content SBS modified asphalt.The four components of base asphalt have strong correlation with the low tem-perature performance of high-content SBS modified asphalt,high-content SBS modified asphalt prepared from asphalt with high saturation content and low asphaltene content has better low temperature flexibility.The greater the number of aromatic rings of the base asphalt,the better the anti-aging performance of the pre-pared high-content SBS modified.
