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。
The road asphalt and the current road asphalt standard refer to the rationality of the target. The existing road asphalt standards and the relationship between road asphalt standards and production are analyzed. Through the relationship between penetration rate, softening point and ductility index of road asphalt produced by different production processes of different crude oil, it is pointed out that ductility does not have a clear correspondence with penetration. Discussed in the GB / T15180-94 standard with a degree of 20 into the interval for the production may cause problems. Proposed amendments to common and high-grade road asphalt indicators.
