摘要
分别针对沥青的三大检测指标——针入度、软化点、延度的定义及应用等进行了介绍,并阐述了近年来国内外对三大指标的研究进展及成果,指出了现行沥青标准的局限性,以期促进沥青材料相关研究。
The paper introduces the definition and application of three checking indexes of asphalt,that is the needle penetration,the softening point and ductility,illustrates the recent research results and development on the three indexes of asphalt at home and abroad,and points out the limitation of the asphalt standards,so as to enhance the relative research on asphalt materials.
