沥青稠度

沥青稠度指标与重载交通车辙试验相关性分析

Relativity Analysis Between Asphalt Consistence Index and Heavy Load Wheel Rutting Test

沥青稠度测试仪的研制和开发

Development of consistency testing system

45℃或60℃稠度试验以及与之相对应的车辙试验表明，以普通沥青的稠度和改性沥青回归后的稠度能比较好的反映沥青抵抗高温的能力。

The result shows that 45 ℃ or 60 ℃ consistency test and rut test show the consistency of unmodified asphalt and the regression viscosity of modified asphalt can appraises more usefully the asphalt high-temperature performance .

最后，给出了沥青纯黏性稠度和稠度-温度指数标准的建议值。

The recommended values of the two proposed indexes are finally presented .

对沥青结合料常用高温性能指标进行了分析，在得出现有沥青高温指标均存在不足的基础上，引入了评价沥青高温性能的稠度指标。

Based on the analysis of general indexes used to appraise the asphalt high-temperature performance , it was found that they all have shortcomings and introduced consistency of asphalt which considered to appraises more usefully the asphalt high-temperature performance .
