This paper studies the properties of the blends composed of DCLR (direct coal liquefaction residue) and asphalt using two different processing methods, compares the regulation that the DCLR additive content and processing method take influence on the high-temperature properties, low-temperature properties and durability of the blends. It is found that the DCLR can improve the high-temperature properties of asphalt but degrade its low-temperature properties. The properties of blends composed of DCLR, asphalt and furfural extract oil are tested and analyzed by adding a certain amount of furfural extract oil into it, which shows that adding DCLR can improve the high-temperature properties of asphalt and reduce its low-temperature properties but can hardly cause any impact on the properties of the blends. In addition, the processing method has a direct influence on the properties of blends.
