Viscoelastic response of aged asphalt cements

Schweyer, H.E. / Majidzadeh, K.

Viscoelastic response of asphalt cements at 32 F was investigated; cylindrical asphalt specimens were subjected to creep test and strain-time data were obtained; using curve-fitting techniques, viscoelastic parameters characterizing aged and unaged asphalts at selected temperature were calculated; dynamic response of asphalts was obtained by transforming strain-time data into frequency domains; analysis indicates that aging results in development of initial elastic deformation mechanism and increase in coefficient of viscous traction.
