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.
Abstract:
In order to study the performance of direct coal liquefaction residue (DCLR) modified asphalt mixtures, 10% DCLR (mass ratio to base asphalt) modified asphalt mixtures and composite DCLR (2% SBS+15% rubber powder+10% DCLR) asphalt mixtures were prepared, and their performance was compared with hot mix asphalt mixtures and SBS modified asphalt mixtures. The experimental results showed that the addition of DCLR can improve the high-temperature stability and water stability of asphalt mixtures, But there is damage to its low-temperature performance; The low-temperature performance of composite DCLR asphalt mixture has been greatly improved, and its high and low temperature performance and water stability are significantly higher than those of SBS modified asphalt mixture
