| 摘 要： | 研究了不同改性剂处理的硫酸钙晶须用量、沥青改性工艺因素以及基质沥青属性等对道路沥青性能的影响规律.结果表明,改性后的硫酸钙晶须能明显提高沥青的软化点,降低沥青的针入度,并且随改性剂添加量的增加沥青软化点逐渐增加,其针入度逐渐减小.本研究为沥青改性提供了一类新材料,同时也为硫酸钙晶须的应用研究奠定了基础.

| Abstract: | The effects of modified calcium sulfate whisker's dosage, asphalt and its modified techniques factors on the performance of asphalt were studied. Experiment results indicated that softening point of asphalt can enhance and its penetration would fall by adding modified calcium sulfate whisker. This study provided a new kind of modifying material for asphalt, at the same time it established a foundation for calcium sulfate whisker's application study. |
