| 摘 要： | 对道路沥青及现行道路沥青标准指旨标合理性进行了讨论，并对现行的道路沥青标准的制定、道路沥青标准与生产之间关系进行了分析。通过不同基属原油经不同生产工艺生产的道路沥青针入度、软化点、延度指标之间的关系，指出延度与针入度没有比较明确的对应关系．讨论了ＧＢ／Ｔ１５１８０—９４标准中以升入度２０为间隔进行的分级可能对生产造成的问题．提出了普通和高等级道路沥青指标的修改建议。

| Abstract: | The specificafion of paving asphalt, formulation of paving asphalt standard and the relationship between the technical indexes of paving asphalt and paving asphalt production was discussed in the paper. The penetration,softening point and ductility of paving asphalt produced by diferent process was compared. It was showed that the penetration of paving asphalt is corresponding with its softening point. The penetration indexes of current paving asphalt standard(GB/T15180-94) may be caused some difficulty for the paving asphalt producer. Suggestion on modification of current paving asphalt specification is given. |
