For any given asphalt, substantial differences are observed for the net adsorption, i.e., amount of asphalt remaining on the aggregate surface after desorption by water, on different aggregate types. Changes to the aggregate surface by modification can result in changing the net adsorption. The extent of change is dependent upon the chemistry and degree of coverage of the modifier. Addition of antistripping agents to the asphatl results in a lowering of both the initial amount of asphalt adsorbed as well as the amount desorbed. This methodology is being developed into a test method for selecting good performing asphalt-aggregate pairs.
