Study on the Performance of Direct Coal Liquefaction Residue Modified Mixture Asphalt

[This draft version of “Study on the Performances of Direct Coal Liquefaction Residue Modified Mixture Asphalt” (DOI 10.1061/9780784413364.039) was erroneously included in the published proceedings.] The properties of the two different blends composed of direct coal liquefaction residue (DCLR) and a binder using two processing methods are studied in this paper. One processing method is to blend powdered DCLR and a binder, and the other is to blend molten DCLR and a binder. The optimum adding content of DCLR is determined using a PG system. Furfural extract oil is used to improve the low-temperature properties of the blends. The performance of DCLR-modified mixture asphalt with the two different blends is also studied in this paper. At first, the DCLR-13 was designed using the Marshall method. Second, the rutting test, freeze-thaw splitting test, and low-temperature bending test was conducted on the DCLR-13. Finally, the performance of the DCLR-13 with the two different blends were evaluated and compared. Results indicate that the performance of DCLR-modified mixture asphalt satisfies the specifications, and the processing method has an influence on the performance of DCLR-modified mixture asphalt.
