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.

NOTE 1: Precision depends only on the distribution of random errors and does no
48、t relate to the true value or the specified value. NOTE 2: The measure of precision is usually expressed in terms of imprecision and computed as a standard deviation of the test results. Less precision is reflected by a larger standard deviation. NOTE 3: “Independent test results“ means results obta
49、ined in a manner not influenced by any previous result on the same or similar test object. Quantitative measures of precision depend critically on the stipulated conditions. Repeatability and reproducibility conditions are particular sets of extreme conditions. DIN EN 12697-12:2008-10 7EN 12697-12:2008 (E) 4 Principle Method A: A se
