Abstract
DAMAGE TO ASPHALT PAVEMENTS OWING TO STRIPPING OF ASPALT CEMENT FROM AGGREGATE IN THE PRESENCE OF WATER HAS PRODUCED SERIOUS DISTRESS, REDUCED PERFORMANCE, AND INCREASED MAINT NTENANCE FOR PAVEMENTS IN THE UNITED STATES, AS WELL AS OTHERAREAS IN THE WORLD. THE PHENOMENON OF STRIPPING HAS BEEN STUDIED BY MANY INVESTIGATORS DURING THE PAST 50 YEARS. THE THE HIGHWAY RESEARCH BOARD, IN JANUARY, 1971, PLACED THE SUBJECT, "STRIPPING OF ASPHALT CEMENTS IN BITUMINOUS M S MIXTURES," AS THE HIGHEST PRIORITY PROBLEM OF 52 RESEARCH STUDIES THAT WERE DESIRABLE. IN 1982, THE ASSOCIATION OF A ASPHALT PAVING TECHNOLOGIESTS ORGANIZED A SYMPOSIUM ON A SINGLE CLASS OF ADDITIVE MATERIALS, NAMELY "ANT-STRIPPING ADDITIVES," WHICH ARE USED TO PROMOTE ADHESION BETWEEN ASPHALT AND THE SURFACE OFMINERAL AGGREGATES. WHILE PROBLEMSASSOCIATED WITH STRIPPING ARE UNIVERSALLY RECOGNIZED, A TESTMETHOD TO DETERMINE THE DEGREE OF ASPHALT STRIPPING, AND PROCEDURES TO OVERCOME THE PROBLEM ELUDE THE PROFESSION. THE RESEARCH PROPOSED HEREIN WOULD PROVIDE THE BACKGROUND TO DEVELOP AN IMPROVED TEST METHOD TO (1) DETERMINE THE SUS CEPTIBILITY OF A MIX TO ASPHALT STRIPPING, AND (2) EVALUATE PROCEDURES, PARTICULARLY THE USE OF ADDITVIES TO OVERCOME THE TENDENCY FOR STRIPPING.
