沥青低温性能评价试验方法讨论

Progress report of asphlat low-temperature testing method

沥青是一种温度敏感性材料,在温度较低时呈现脆性,影响了沥青路面低温抗裂性能。文章对沥青低温性能评价方法及评价指标进行了介绍,并根据伯格斯模型认为沥青低温粘度测试方法是表征沥青低温性能的最佳测试方法。

This paper introduced asphalt low temperature performance testing methods,their merits and demerits are discussed.Based on the Burgers model,the beterr testing method is the testing of asphalt low temperature viscosity.
