摘要
橡胶颗粒的加入,对沥青混合料的马歇尔试验特征值产生显著影响。本文通过灰色关联熵分析理论评价马歇尔试验特征值对橡胶颗粒沥青混合料高温稳定性的影响。研究认为:在连续密级配中,稳定度、饱和度、流值、沥青用量对高温稳定性影响显著;毛体积密度、间隙率、空隙率次之,这为橡胶颗粒沥青混合料的配合比设计和高温稳定性的改善提供依据。
The rubber particles joining have a significant impact on the Marshall stability and flow of mixture, this paper discussion Marshall characteristic parameters impact on high temperature of rubber particles asphalt mixture by grey correlation entropy. Re- search shows ：on continuous gradation, Stability, saturation, flow, asphalt content have significant impact on high temperature , bulk density, clearance rate, voids are samaller than them. That provide a basis for the rubber particles of asphalt mixture gradation desig- ning and high temperature stability improvement.
