Which material parameters are needed when modelling viscoelasticity?

Dear all,
I am quite a new comsol user and am trying to model rutting in an asphalt solar collector. Due to the viscoelastic nature of asphalt, i am using the viscoelastic interface from the structural mechanics module. Here 3 models are available and I want to use both the kelvin-voigt model and the SLS model (not simultaneous ofcourse). In the SLS model the shear modulus "Gv" is asked, however I wasn't able to find anywhere whether this is the ordinary shear modulus, the complex shear modulus or the loss/storage modulus. I have kind of the same problem with the young's modulus, how do I implement the complex young's modulus rather than the normal one?
With kind regards,
De Keninck Matisse
