適用范圍：This European Standard describes three test methods for determining the effect of saturation and acceleratedwater conditioning.These methods can be used to evaluate the effect of moisture with or without anti-stripping additives includingliquids, such as amines, and fillers, such as hydrated lime or cement:-- method A uses the indirect tensile strength of cylindrical specimens of bituminous mixtures;-- method B uses the compression strength of cylindrical specimens of bituminous mixtures;-- method C defines the bonding value of soft asphalt mixtures 1 h after mixing, where the bonding of bitumen and aggregate can be equated to a bonding value.Method A and method B give the same result on average. However, if the slenderness of the specimens isless than 0,5, method B is not suitable.Method C is suitable for soft asphalt mixtures with bitumen of viscosity at 60 ℃ of 4000 mm2/s or less, forwhich methods A and B are not suitable.NOTE Methods A and B are suitable for soft asphalt mixtures with bitumen of viscosity at 60 ℃greater than4000 mm2/s.
