Herein, tannic acid‐terephthalyl chloride (TA‐TPC) was prepared and was applied for the preparation of TA‐TPC‐Rubber to composite styrene butadiene styrene (SBS)‐modified asphalt (SBSMA). Fourier transform infrared spectroscopy and scanning electron microscopy indicated that TA‐TPC successfully attached to the surface of rubber powder (RP), which improved the bonding between RP and SBSMA. Fluorescence microscopy analysis showed that TA‐TPC‐Rubber formed a complete crosslinking network structure in SBSMA, while thermogravimetry analysis proved the higher thermal stability of TA‐TPC‐Rubber/SBSMA. Dynamic shear rheometer and multi‐stress creep recovery tests confirmed that compared with SBSMA, the storage modulus (G') and loss modulus (G") of 12% TA‐TPC‐Rubber/SBSMA at 46°C were increased by 37.14% and 34.36%, respectively, the recovery rate was increased by 35.49% (0.1 kPa) and 31.91% (3.2 kPa) while the average creep compliance was decreased by 68.67% (0.1 kPa) and 59.87% (3.2 kPa). The phase segregation test proved that the compatibility between RP and SBSMA was improved by the modification of TA‐TPC, and the difference between the upper and lower softening points were reduced by 53.85%. The findings of this study can be of great significance for designing modified asphalt from cost‐effective raw materials through a convenient process for highways and construction applications.
