DIN EN 12697-12:2008-10 5EN 12697-12:2008 (E) 1 Scope This European Standard describes

    34、 three test methods for determining the effect of saturation and accelerated water conditioning. These methods can be used to evaluate the effect of moisture with or without anti-stripping additives including liquids, such as amines, and fillers, such as hydrated lime or cement: method A uses the in

    35、direct 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

    36、a bonding value. Method A and method B give the same result on average. However, if the slenderness of the specimens is less than 0,5, method B is not suitable. Method C is suitable for soft asphalt mixtures with bitumen of viscosity at 60 C of 4000 mm2/s or less, for which methods A and B are not s

    37、uitable. NOTE Methods A and B are suitable for soft asphalt mixtures with bitumen of viscosity at 60 C greater than 4000 mm2/s. 2 Normative references The following referenced documents are indispensable for the application of this document.
