38、t method 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 steel brush mounted in a mixer. The material loss of the specim
39、en is a measure of the resistance to that fuel for that bituminous mixture. NOTE The test is normally carried out with jet fuel. 2 Normative references The following referenced documents are indispensable for the application of this document.

43、 mixture 4 Principle A cylindrical test specimen with a known mass is immersed partly in a bath with the specified fuel for a specified period of time. For bituminous mixtures with paving grade bitumen this period is 24 h; for mixtures with a polymer-modified bitumen a 72 h period is used. After rem
44、oval from the bath, cleaning with water and drying for 24 h in a ventilated oven at 25 C, the loss of mass of the specimen is measured and the immersed surface is visually inspected. The type of affection and the material loss of the immersed surface are also recorded. Then the test specimen is put
45、in a steel mould with the immersed surface up. At the bottom of the specimen a pneumatic cylinder pushes the immersed surface onto a steel brush, which is moving in epicycloids passages over the surface. After 30 s the brushing stops and the specimen is removed from the mould. Then the loss of mass
46、is measured and the brushed surface is visually inspected. After that the specimen is put back in the mould and the same procedure is carried out again after 30 s and after 60 s, when the brushed surface is visually inspected again. The total brushing time is 120 s (two brushing periods of 30 s and
47、one of 60 s). The material loss after the immersion and/or the brush test is a measure for the resistance to that particular fuel.

48、with a polymer-modified binder is longer than for mixtures with paving grade bitumen. This in chosen because mixtures with a PMB most often have already a higher resistance to fuel than mixtures with paving grade bitumen. To find differences between mixtures with various PMBs a more severe test is n
49、eeded. This can be accomplished by using a longer immersion time. To find differences between mixtures with paving grade bitumen and PMBs and immersion time of 24 h can be chosen. NOTE 2 For the brushing, a Hobart mixer can be used. 5 Equipment 5.1 Fume cupboard During the brush tests aggregate parts with a
