STIFFNESS HISTORY OF ASPHALT CONCRETE SURFACES IN

asphalt concrete stiffness should be in a form that can be programmed. It is an established fact that asphalt concrete is neither elastic nor viscous but vis­ coelastic; i.e., its stiffness is a function of temperature and loading time. Moreover, the aging of asphalt adds an important dimension to the stiffness of the asphalt concrete.
