路面越来越多地采用改性沥青,根据沥青粘度的物理意义研制出更能反映沥青粘稠特性的稠度仪。文章利用沥青稠度试验仪对不同品牌的基质沥青和改性沥青的粘稠性能进行系统的测试和分析,重点研究了稠度指标与其他沥青高温指标的比较分析。试验结果表明,沥青稠度试验仪不仅具有精度高、操作简单,对试验人员要求低的特点;而沥青的稠度和稠度-温度指数可有效的反映沥青的高温性能和感温性;因此,沥青稠度试验仪具有较高的推广价值。
Pavement more and more use of modified asphalt, according to the physical meaning of asphalt viscosity developed more consistency of the viscosity of asphalt. This paper systematically tests and analyzes the viscosities of different brands of matrix asphalt and modified asphalt by using asphalt consistency tester, and focuses on the comparative analysis of the consistency index and other asphalt high temperature indexes. The test results show that the asphalt consistency tester not only has the characteristics of high precision, simple operation and low requirement to the experimenter. The consistency and consistency of asphalt - the temperature index can effectively reflect the high temperature performance and temperature sensitivity of asphalt; therefore, the asphalt consistency Tester has a higher promotional value.
