摘要： 将沥青胶浆视为由沥青基体和矿粉夹杂相组成的两相复合材料,基于简化的Christensen-Lo模型有效模量解答,应用广义Maxwell模型和黏弹性对应原理,建立了沥青胶浆动态剪切模量预测的细观力学模型,采用不同种类沥青胶浆的动态剪切流变仪(DSR)试验对预测值进行了校正,并分析了模型参数对预测值的影响。结果表明,矿粉体积分数为10%时,预测值与试验值较为一致,但在20%和30%体积分数下,预测值小于试验值;预测偏差主要归因于较高体积分数下矿粉颗粒间的相互作用,采用逾渗理论对提出的预测模型进行修正,据此得到的预测值与试验值较为吻合;矿粉弹性模量对预测值的影响较小,增大矿粉体积分数可以有效提高预测值。

Abstract: Asphalt mastic is regarded as a two-phase composite with asphalt matrix and embedded-matrix coated mineral filler. A micromechanical model is established to predict the dynamic shear modulus of asphalt mastic. The generalized Maxwell model and elastic-viscoelastic correspondence principle are used in this model based on the simplified Christensen-Lo model solutions. The DSR tests for asphalt mastic are conducted to verify the proposed model, and the model parameters affecting the modulus prediction are explored. The results show that, compared with measured modulus, the predicted modulus is acceptable for asphalt with 10% filler volume fraction. However, with filler volume fractions of 20% and 30%, the predicted moduli are smaller than the measured ones, and the discrepancy mainly results from the interaction between filler particles at higher volume fraction. The percolation theory is then introduced to obtained a new modified model, by which the predicted moduli agree with measured ones. The elastic modulus of the fillers has a slight effect on the predicted moduli, and the increase in volume fraction of filler leads to the increase in the predicted modulus.
