Dynamic Modulus of Hot Mix Asphalt - Rutgers CAIT

Feb 05, 2019  Dynamic Modulus of Hot Mix Asphalt. One of the most critical parameters needed for the upcoming Mechanistic Empirical Pavement Design Guide (MEPDG) is the dynamic modulus (E*), which will be used for flexible pavement design. The dynamic modulus represents the stiffness of the asphalt material when tested in a compressive-type, repeated load test.

It can be seen that the ∣E ∗ ∣ value of HMA mixtures kept increasing as the dynamic modulus of asphalt mastic increased. The reason for this can be attributed to the fact that asphalt mastic is the softest constituent in the mixture.
