摘要
为了研究煤直接液化残渣(direct coal liquefaction residue,DCLR)改性沥青混合料性能,制备10%DCLR(与基质沥青质量比)改性沥青混合料和复合DCLR(2%SBS+15%橡胶粉+10%DCLR)沥青混合料,并与热拌沥青混合料以及SBS改性沥青混合料性能对比.试验结果表明:DCLR的掺入可以提高沥青混合料的高温稳定性和水稳定性能,但对其低温性能有损伤;复合DCLR沥青混合料的低温性能得到了很大程度的提高,其高低温性能和水稳定性明显高于SBS改性沥青混合料.
To study the performance of the DCLR modified asphalt mixture, the 10% DCLR （by mass of SK- 90 asphalt） modified asphalt mixture and the compound DCLR （2% SBS ＋ 15%rubber powder ＋ 10% DCLR） modified asphalt mixture are prepared. The performances of the SK-90 asphalt mixture, SBS modified asphalt mixture are compared to 10% DCLR modified asphalt mixture and compound DCLR modified asphalt mixture. The results show the DCLR can improve the high-temperature performance and water stability of asphalt mixture but the low-temperature performance is damaged. The low-temperature performance of the compound DCLR modified asphalt mixture is improved greatly. Meanwhile, the high-temperature performance, low-temperature performance and water stability of compound DCLR modified asphalt mixture are higher than those of SBS modified asphalt mixture obviously.
