摘要
介绍了道路沥青的组成、性质和评价指标,以及煤直接液化残渣的来源和组成特性。简单介绍了煤直接液化残渣制备改性沥青的工艺,对国内的研究现状进行总结及分析,总结前人研究成果,并指出煤直接液化残渣作为沥青改性剂在实验研究中是可行的,但能否适用于工业化应用还需要开展更加深入的研究性工作。
The composition, properties and evaluation index of asphalt roads were introduced, as well as the source of direct coal liquefaction residues and composition properties. The chemical technology of preparation of modified asphalt from direct coal liquefaction residue was reviewed. The domestic research status and results of previous studies were summarized and analyzed, and the direct coal liquefaction residue as asphalt modifier in the experimental study was feasible that was pointed out. If it can be applied to the industrial application also needed to carry out research work more deeply.
