Embodiment 1
[0030] Step 1. Perform dynamic frequency sweep test, static creep test and stress relaxation test on asphalt with dynamic shear rheometer, and collect dynamic modulus |G during the test * |, phase angle δ, creep compliance J and relaxation modulus G and other basic dynamic and static data;
[0031] Step 2, analyze and process the dynamic frequency scanning test data obtained in step 1, establish the viscoelastic function master curve according to the time-temperature equivalent principle, and draw the dynamic modulus master curve (such as figure 1 shown) and phase angle main curve (as figure 2 shown), for the static creep and relaxation test data, the creep compliance-time curve is plotted with time as the abscissa and creep compliance as the ordinate (such as image 3 shown), draw the relaxation modulus-time curve with time as the abscissa and relaxation modulus as the ordinate (such as Figure 4 shown);
[0032] Step 3: Establish the asphalt viscoelastic model, select th...
