For Abaqus modelling of asphalt concrete as visco elastic material, the data that can be inputted into the material properties is in the form prony series. Usually dynamic modulus test is conducted to input the respective prony series values. The alternate option in abaqus material properties is to input the creep data. Whether any standards or protocols tests are there to input the test data directly?
I am interested to your question (similar to my case).and will explain in detail soon. Bit hurry for this time, please consult me.
May be, these references you can use in your study:

AASHTO T322 provides a creep compliance testing protocol in indirect tension mode. There is a calculation method in the standard, as well as the viscoelastic representation featured in several places, including a NCDOT report by Kim, Daniel, and Wen (2002).
AASHTO T322 provides a creep compliance testing protocol in indirect tension mode or ASTM D 4123..
