Viscoelasticity is one of the important characteristics for gussasphalt.The objective of this study is to find the correct viscoelastic material parameters for the novel gussasphalt applied in the 4th Changjiang(Yangtze)River Bridge based on the modified Burgers model.In this study,we first converted the viscoelastic parameters of modified Burgers model into the explicit Prony series form of the shear relaxation modulus using the Laplace transform.Thus they could be transformed into the required material pa...
