沥青混合料高温稳定性能研究

Asphalt High Temperature Stability Performance Study

通过对沥青混合料高温稳定性影响因素的灰色关联分析,在所知数据不多的条件下,计算出车辙大小与马歇尔力学特征值的灰色关联度,找出了影响沥青混合料高温稳定性各项因素的关联顺序,并对各项影响因素分别进行了研究,分析各种马歇尔力学特征值对混合料高温性能的影响。这种方法克服了一般数理统计分析中的不足,为沥青混合料的设计、评价、控制、和高温性能的改善提供了依据。

Through gray association analysis of asphalt high temperature stability performance influence factors, under condition of not much known data, the gray association degree between size of mt and Marshall mechanical characteristics value is calculated, and the association sequence of all factors that influence asphalt high temperature stability is found out , and the respective studies are conducted to all influential factors to analyze influence of all Marshall mechanical characteristics values to the high temperature stability performance of asphalt mixture. This method overcomes the disadvantages in general mathematical statistics analysis, and provides basis for asphalt design, evaluation, control and its high temperature stability performance melioration.
