BS EN 12697-41:2013EN 12697-41:2013 (E) 6 1 Scope This European Standard specifies a test method to determine the resistance of bituminous materials
36、to de-icing fluids such as solutions of acetate and formate. The procedure determines the surface tensile strength of a specimen of asphalt which has been stored in de-icing fluid. This European Standard is primarily used as a test on asphalt to be laid on airfields, but it can be used for asphalt t

41、cument, the following terms and definitions apply. 3.1 surface tensile strength tensile stress at maximum force when testing the surface tensile strength according to this test method 4 Principle Testing is performed on a sawn cylindrical specimen of asphalt on which a well-defined test surface has
42、been drilled out in the bituminous mixture to a depth of about 5 mm. Four specimens are stored and four are not stored in a de-icing fluid. A steel plate is bonded to the test surface of each specimen in turn. During testing, the plate is pulled off with a tensile force increasing at a rate of 200 N
43、/s, the force being applied perpendicular to the test specimen surface. The tensile force at failure load and the mode of failure are recorded. The results are compared with those for specimens which have not been stored in de-icing fluid. BS EN 12697-41:2013EN 12697-41:2013 (E) 7 5 Apparatus 5.1 Ve
