Abstract

Open-graded friction course mixtures were evaluated in the laboratory to determine the potential for stripping. A boiling test was used to measure the potential for stripping in mixtures containing three asphalts used in New Mexico with and without both liquid antistripping additives and hydrated lime. Mixtures were also evaluated with the same three binders after modification with a polymer. All testing was conducted on mixtures after the optimum binder content was determined by using the open-graded friction course mix design procedure described by FHWA.

RESULTS of this study indicate that optimum asphalt content of open-graded friction course mixtures varies depending on the asphalt, antistripping agent type, and quantity and whether the binder is polymer modified. Stripping potential as measured by the Texas Boiling Test was significantly reduced after addition of antistripping agents to the asphalt or aggregate and after polymer modification of the binders.
