doi:10.12052/gdutxb.230008

摘要/Abstract

摘要： 零剪切黏度(Zero-shear Viscosity, ZSV)是表征沥青抵抗永久变形能力的高温性能评价指标。为明确不同测试方法及计算模型对高模量改性沥青的ZSV计算值的影响及适用性，以推广高模量改性剂在道路工程的应用，采用动态剪切流变仪对基质沥青(Base Asphalt, BA)和含不同质量分数改性剂的高模量改性沥青(K1-HMB)进行60 ℃频率扫描试验和60 ℃稳态流动试验，并采用Cross流变模型及Carreau流变模型分别拟合沥青的ZSV，最后采用灰色关联分析法探讨ZSV与软化点之间的关联程度。结果表明：BA及K1-HMB属于伪塑性流体，在加载频率作用下均呈现剪切变稀的特征；含0.6%改性剂的K1-HMB具有最高的弹性恢复能力，K1-HM改性剂的建议质量分数为0.4%～0.6%；60 ℃频率扫描试验结合Cross模型计算的ZSV拟合值具有最高的可信度，可作为高模量改性沥青高温性能的评价指标。

Abstract: Zero-shear viscosity (ZSV) is an evaluation index for viscosity of asphalt to permanent deformation at high temperature. To investigate the applicability and influence of different test methods and calculation models on ZSV fitting for high modulus modified asphalt, and to promote the application of high modulus modifiers in road engineering, dynamic shear rheometer was used to perform 60 ℃ frequency sweep test and 60 ℃ steady flow test on base asphalt (BA) and high modulus modified asphalt (K1-HMB) with different modifier content. ZSV of test materials was fitted by Cross rheological model and Carreau rheological model. Finally, grey correlation analysis was used to further explore the degree of correlation between ZSV and softening point. The results show that BA and K1-HMB are pseudo-plastic fluids and both exhibited shear thinning characteristics under loading frequency. K1-HMB with 0.6% content had the highest elastic recovery capacity, and the recommended content of K1-HM modifiers was 0.4%～0.6%. The ZSV fitting value based on the 60 ℃ frequency sweep test combined with Cross model had the highest reliability and could be used as an evaluation index of the high temperature performance of high modulus modified asphalt.
