Asphalt Durability – Pavement Interactive

Asphalt durability is a measure of how asphalt binder physical properties change with age (sometimes called age hardening). In general, as an asphalt binder ages, its viscosity increases and it becomes more stiff and brittle. Age hardening is a result of a number of factors, the principal ones being (Vallerga, Monismith and Grahthem, 1957 [1 ...
