沥青胶浆高低温性能评价体系的研究

Research on the High-and-Low Temperature Performance Evaluating System of Asphalt-Mineral Filler Mastic

在分析现有沥青结合料多种高低温性能评价方法的基础上,应用灰色关联熵分析方法建立沥青胶浆与沥青混合料实际路用性能之间的关联性,最终得出应用动态剪切流变仪测得的重复蠕变劲度的粘性部分和应用弯曲梁流变仪测得的蠕变劲度模量分别作为沥青胶浆高低温性能的评价指标。

Asphalt-mineral filler mastic is a special binder, which consists of asphalt and mineral filler. It is one of the most important components of asphalt mixture. And how to evaluate its pavement performance rationally is a hotspot in research. Therefore, based on the analysis of existing many high-and-low temperature performance evaluating methods, the relationship between pavement performance of asphalt-mineral filler mastic and asphalt mixture with grey relation entropy method of grey relation analysis were studied, then offer viscous component of the repeat creep stiffness which was tested by DSR and creep stiffness modulus which was tested by BBR accordingly for the parameter to evaluate the high and low temperature performance of asphalt-mineral filler mastic.
