摘要: 环球法测定超高软化点沥青的软化点存在不足之处,对环球法中的导热介质及样品成型方法进行改进,从而更准确测定软化点≥157 ℃沥青的软化点。 

关键词: 超高软化点沥青, 环球法, 冷压制样

Abstract:

Through experiment, the heat transferring medium and sample forming in the universal method are improved so that more accurate softening point of the asphalt with softening point ≥157 ℃ can be determined.
