摘要
综述了煤直接液化残渣(DCLR)在沥青改性剂方面的研究进展,阐述了其物态属性,通过对比青川岩沥青以及特立尼达湖沥青2种天然沥青,分析各改性剂优缺点,论述了煤直接液化残渣作为沥青改性剂在煤炭清洁高效利用技术的重要意义。从相容性理论概述,从复合改性角度介绍了目前其作为沥青改性剂的研究进展。最后,对煤直接液化残渣作为沥青改性剂方向的未来发展进行展望,在改性体系方法设计、材料行为机理认识以及路面功能化等方面提供借鉴和参考。
The application of coal direct liquefaction residue(DCLR)in the direction of asphalt modifier was summarized,its physical properties was expanded,advantages and disadvantages of each modifier by comparing Qingchuan rock asphalt and Trinidad Lake asphalt was analyzed and the important significance of coal direct liquefaction residue as asphalt modifier in the clean and efficient utilization of coal was discussed.From the perspective of compatibility theory,the research and development of asphalt modifier were introduced from the perspective of composite modification.Finally,the future development of coal direct liquefaction residue as asphalt modifier was prospected to provide reference and reference in the design of modification system method,the understanding of material behavior mechanism and pavement functionalization.
