摘要

软化点是评价沥青高温性能的重要指标之一。但部分改性沥青软化点在老化前后变化不规则，且与其他高温指标相关性不高，一直是研究者关注的问题。为此，本工作以苯乙烯-丁二烯-苯乙烯改性沥青为研究对象，以长、短期老化为条件，通过对软化点试验的改进，并结合温度敏感相关、差示扫描量热、动态剪切流变试验，探讨改进软化点试验相关指标的意义，为沥青性能评价体系提供新的思路。

Research on Temperature Stability of Asphalt Based on Improved Softening Point Test

The softening point is one of the important indexes used to evaluate the high-temperature performance of asphalt. However, some modified asphalt softening points show irregular changes before and after aging, and the correlation with other high-temperature indexes is not high, which has been a concern for researchers. To this end, this work takes styrene-butadiene-styrene–modified asphalt as the research object and long- and short-term aging as the condition, through the improvement of softening point test and combined with the temperature-sensitive correlation, differential scanning calorimetry, and dynamic shear rheology tests, to explore the significance of improving the softening point test–related indicators to provide new ideas for the asphalt performance evaluation system.

期刊介绍： This journal is published in six issues per year. Some issues, in whole or in part, may be Special Issues focused on a topic of interest to our readers. This flagship ASTM journal is a multi-disciplinary forum for the applied sciences and engineering. Published bimonthly, the Journal of Testing and Evaluation presents new technical information, derived from field and laboratory testing, on the performance, quantitative characterization, and evaluation of materials. Papers present new methods and data along with critical evaluations; report users'' experience with test methods and results of interlaboratory testing and analysis; and stimulate new ideas in the fields of testing and evaluation. Major topic areas are fatigue and fracture, mechanical testing, and fire testing. Also publishes review articles, technical notes, research briefs and commentary.
