Abstract—The complex moduli relationship related mixture
moduli to temperature and time rate of loading has been an
integral part of several mechanistic-empirical (M-E) design
procedures used throughout of the world. Seven asphalt
concrete mixtures of different types of polymer modified
binders (PMB) were produced in a laboratory to modify
performance of asphalt mixture. The main role of this research
is to evaluate the influence of these polymer modifiers on the
pavement performance of asphalt mixture with the dynamic
modulus, |E*| of hot-mix asphalt (HMA) mixture indicator in a
laboratory test for Mainroad Western Australia and Fulton
Hogan. In this study, the influence of temperature, loading
frequency, and confining pressure on the dynamic
characteristic of asphalt mixture were analysis, master curves
of dynamic modulus of HMA mixtures were developed and
data’s were interpreted. Results showed that AC10 5.7% A35P
(EVA) M7 B5, AC10 5.7% C450 M10 B5 and AC10 Multi
600/700 M5 B4 mixes method were the more efficient and
effective in all categories of asphalt performance measures for
strength and durability of HMA as compared to others polymer
modifiers. A very good correlation (R2 = 1) was found for each
polymer modifier. This suggested that laboratory test using a
various temperatures and loading frequencies can improve
pavement mix design, lab and field control and assurance. A
strong correlation between binder viscosity and temperature
[R2 = 1] for polymer modified asphalt mixture.
