摘要
简述了煤沥青的组成和性质,综述了煤沥青改性后用作筑路材料、煤沥青和石油沥青混合料用作筑路材料的研究进展及其毒性防治,展望了筑路用煤沥青材料的研究新方向及应用前景。
The composition and properties of the coal tar pitch（CTP） were reviewed and the advantages and disadvantages of the CTP used as road paving material was discussed in this paper.To improve the properties mentioned above,a modified paving material combining coal tar pitch with petroleum asphalt was investigated,and its application prospect was discussed.
