Abstract A DCLR-based direct-addition composite modifier was developed to promote the high-value utilization of direct coal liquefaction residue (DCLR) and simplify its application in asphalt modification. The effects of DCLR, SBR, aromatic oil, and crumb rubber on the rheological properties of asphalt mastic were evaluated using an L9 (34) orthogonal experimental design, dynamic shear rheometer (DSR), bending beam rheometer (BBR), fluorescence microscopy (FM), and analysis of variance (ANOVA).
