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.
