| 摘 要： | 优质路面(Superpave)沥青混合料组成设计方法中对永久变形的预测采用的方法和设备是一般试验设计单位无法满足的。利用沥青路面分析仪(APA)和马歇尔稳定仪研究了影响沥青混合料抗车辙性能的各个因素,并分析了间接拉伸强度和混合料的抗车辙性能的关系,为合理预测沥青混合料的车辙病害提供了重要依据。

| Abstract: | As a result of the high cost of the performance testing equipment and well-trained,experienced personnel required in using the Superpave mix design procedure,most state highway agencies can not meet the condition.In this paper rutting potential was evaluated with the Asphalt Pavement Analyzer(APA) and indirect tensile strength(IDT Strength) was measured using the Marshall Stabilometer with a split tensile head.The Relationship between IDT Strength and Rutting Potential was given.The purpose of this paper is to provide references for future research of rutting in asphalt pavements and for designs of asphalt pavements. |

| Keywords: | asphalt mix rutting potential indirect tensile strength |
