BS EN 12697-43:2014EN 12697-43:2014 (E) 7 1 Scope This European Standard specifies a test meth

40、od to determine the resistance of a bituminous mixture or pavement to fuels. The procedure involves initial soaking of a test specimen made in the laboratory or cored from a pavement in a fuel, followed by a brushing period with a brush test device. The material loss of the specimen is a measure of

41、the resistance to that fuel for that bituminous mixture. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

45、 applies. 3.1 fuels liquid (petroleum product) that might be spilled accidentally or sprayed deliberately onto an asphalt pavement and can cause damage to the asphalt mixture 4 Principle A cylindrical test specimen with a known mass is immersed partly in a bath with the specified fuel for a specifie

46、d period of time. After removal from the bath, cleaning with water and drying for 24 h at 25 C, the loss of mass of the specimen is measured and the immersed surface is visually inspected. Then an abrasive loading is applied onto the immersed surface of the test specimen by a steel brush mounted ont

47、o a brush test device. The steel brush moves in epicycloids passages over the surface. After 30 s the brushing stops and the specimen is removed. The loss of mass is measured and the brushed surface is visually inspected. The specimen is then put back and the same procedure is carried out again afte

48、r 30 s and after 60 s, when the brushed surface is visually inspected again. BS EN 12697-43:2014EN 12697-43:2014 (E) 8 The total brushing time is 120 s (two brushing periods of 30 s and one of 60 s). The combined material loss after the immersion and the brush test is the main parameter for the resi

49、stance to the particular fuel. As additional information the material loss after the immersion (chemical loading) and the brush test (mechanical loading) are further informative parameters for the resistance to the particular fuel. 5 Apparatus 5.1 Beaker with glass rod Cylindrical beaker made of glass for soaking the test specimen in the fuel.
