摘　　要：沥青胶结料是高等级道路路面的主要建筑材料,多年来的研究表明,其是一种复杂的热流变材料,常规试验方法不能很好地测出其低温性能。利用MTS(多功能材料试验机)对4种沥青胶结料进行深入试验研究,探讨沥青胶结料的低温性能。研究结果表明,MTS试验是评价沥青胶结料低温性能的一种有效方法,其对更好地了解沥青胶结料的低温性能具有重要意义。Asphalt cement materials are principal building materials for high-grade road pavement, and researches of many years has shown that they are complicated thermoheological materials and their low- temperature performance cannot be well measured by conventional test methods. This paper carries out deep experimental study on four kinds of asphalt cementing materials by means of MTS （multi-function material test set） and investigates low-temperature performance of asphalt cementing materials. The results of study show that MTS test is an effective method to evaluate low-temperature performance of asphalt cementing materials and exhibits important significance for better understanding of low-temperature performance of asphalt cementing materials.
