Abstract: To assess the water sensitivity of asphalt rubber mixtures an experimental study was carried out, in which different types of gap-graded mixtures applied in wearing courses were used. The experimental study compares the results obtained by the test method traditionally used in Portugal - the American army standard MIL-STD-620A – method 104 - with those obtained through the EN 12697-12:2008-method A. The application of the European standard leads to lower values of retained resistance than those obtained with the American army standard and al-lows for a better distinction of the behavior of different mixtures. This paper presents the main results achieved so far, and contributes for the achievement of reference values for water sensi-tivity of gap-graded asphalt rubber mixtures determined according to the European standard EN 12697-12:2008 - method A.
