EN 14693:2006 (E) 4 Introduction The purpose of the test is to determine the behaviour of the bitumen sheet which is in contact with the mastic asphalt during application. EN 14693:2006 (E) 5 1 Scope This European Standard is app
17、licable to bitumen sheets intended for use with a layer of mastic asphalt. This European Standard specifies a test method for the evaluation of the resistance of bitumen sheets to the rising of the bitumen compound at the application of mastic asphalt in a non-floating manner. Note This European Sta
18、ndard could also be used for bitumen sheets intended for use with other asphalt types as a protection layer. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

26、13416, the dimensions of the test specimens are (400 10) mm (400 10) mm. Ensure that the test specimens are without any mechanical damage. The thickness of the sheet, determined in accordance with EN 1849-1, shall be known (reference thickness). Two concrete slabs are required. 4.4 Procedure 4.4.1 C
27、ondition the sand layer, the concrete slab and the test specimen for at least 24 h at (23 2) C. 4.4.2 Place the test specimen onto the concrete slab. Position the frame on top of the test specimen and concrete slab, and fix it with screw clamps. EN 14693:2006 (E) 7 Key 1 mastic asphalt boiler 2 mast

29、4.4.5 Ensure that the temperature of the mastic asphalt on leaving the boiler is (250 3) C before pouring, and also that the pouring height of the mastic asphalt from the upper surface of the test specimen is between 100 mm and 150 mm. Complete the pouring of the mastic asphalt within two minutes, a
30、nd leave to cool for at least eight hours after pouring. After cooling, remove the frame. EN 14693:2005 (E) 8 4.5 Measurements 4.5.1 Determination of surface proportion of any sheet compound specks on the surface of the mastic asphalt 4.5.1.1 Determine the mass of the square partial surface of the t
31、ransparent foil with an area of (50 1) mm (50 1) mm, m1. 4.5.1.2 Visually determine a square partial surface of (50 1) mm (50 1) mm of the mastic asphalt surface, on which the total area taken up by the sheet compound specks holds the biggest share. In case of doubt, the use of UV-C illumination is
32、recommended. 4.5.1.3 Mark the sheet compound specks of this partial surface on transparent foil and cut out the specks. 4.5.1.4 Determine the mass of the cut-out segments of the foil, m2.4.5.2 Determination of the thickness of the sheet after pouring the mastic asphalt 4.5.2.1 Saw the test specimen
33、(made up of the concrete slab, sheet and mastic asphalt) parallel to the lateral face into three equal parts. Use the middle part as a test specimen for further testing. 4.5.2.2 Make fine pencil marks at each 25 mm on both cut surfaces of the test specimen. The first mark shall be made 10 mm from th
34、e edge of the mastic asphalt. Apply the marks vertically to the upper concrete surface on both sides of the sheet. 4.5.2.3 Determine the thickness of the sheet at each pencil mark to an accuracy of 0,1 mm in the stereo optical measuring instrument. In cases of doubt, determine the borderline between
35、 the sheet, the mastic asphalt and the concrete slab respectively with a pointed object. Any mineral particles distributed from the sheet surface protection shall be considered as part of the sheet. 4.5.2.4 Substitute any determined individual value that is bigger than the reference thickness of the
36、 sheet by the reference thickness. 4.5.2.5 Calculate the arithmetic mean of the thickness of each test specimen to an accuracy of 0,1 mm. 4.5.3 Determination of sheet compound inclusions in the mastic asphalt 4.5.3.1 Visually determine at both cutting edges of the test specimen any inclusions of she
37、et compounds, either bonded or not bonded to the sheet. In case of doubt, the use of UV-C illumination is recommended. 4.5.3.2 Such inclusions of a size 7 mm (distance between the extreme points of the inclusions) that are not bonded to the sheet shall be marked and counted accordingly. 4.5.3.3 Shee
38、t compound inclusions of a maximum height 12 mm from the underside of the sheet that are bonded to the sheet, shall be marked and counted accordingly. 4.5.3.4 The total number of both types of inclusions on each test specimen is calculated.
