27、4 Test methods 4.1 Principle The test consists of compacting a defined asphalt layer on a waterproofing sheet laid on a base specimen. It may be carried out in two alternative ways: Method 1: The asphalt layer is laid directly on the sheet bonded to the base specimen; Method 2: A de-bonding interfac

28、e is laid between the base specimen and the sheet and between the sheet and the asphalt layer. After compacting of the test specimen, the waterproofing sheet is recovered for observation of its condition and any perforations. Depending on the results of the observations, the watertightness of the re

29、covered waterproofing sheet should be checked. BS EN 14692:2017EN 14692:2017 (E) 6 4.2 Apparatus and materials 4.2.1 Compaction equipment, as referred to in EN 13375. 4.2.2 Standard equipment and materials, such as, site gas torch, brush, etc. 4.2.3 Oven, with circulating air (without fresh supply),

30、 capable of maintaining (100 5) C 4.3 Preparation of test specimens 4.3.1 General Take samples and test pieces in accordance with EN 13416. 4.3.2 Test specimen with sheet bonded to the base specimen (Method 1) The test specimen is prepared in accordance with EN 13375. The size of the test specimen i

31、s 600 mm 400 mm. 4.3.3 Test specimen with sheet not bonded to the base specimen (Method 2) Place a de-bonding interface between the base specimen and the waterproofing sheet, and on the upper surface of the waterproofing to prevent the asphalt layer adhering to it. For the interface between the base

32、 specimen and the waterproofing sheet, use one non-woven glass fibre sheet of (70 5) g/m2. For the interface between the waterproofing sheet and the asphalt layer mix, use two non-woven glass fibre sheets of (70 5) g/m2. The size of the test specimen is 600 mm 400 mm 400 mm 400 mm, resp. 500 mm 500

33、mm. 4.3.4 Asphalt layer, compaction and test specimens 4.3.4.1 General Lay and compact the asphalt layer mix in accordance with EN 13375. 4.3.4.2 Test specimen with sheet bonded to the base specimen (Method 1) In the case of the sheet bonded to the base specimen, obtain four equal parts by wet sawin

34、g the test specimen, prepared as described in 4.3.1 and 4.3.2. 4.3.4.3 Test specimen with sheet not bonded to the base specimen (Method 2) In the case of test specimens with de-bonding interfaces, let the asphalt layer cool and remove the sheet for visual inspection and testing. 4.4 Procedure 4.4.1

35、Test specimen with sheet bonded to the base specimen (Method 1) 4.4.1.1 Inspect visually the cross-section of the parts of the test specimen to check the sheet/asphalt layer interface, and whether any binder from the sheet is bleeding into the asphalt layer. 4.4.1.2 Heat two parts of the test specim

36、en in an oven at (100 5) C for (120 5) min. 4.4.1.3 Separate the sheet manually from the base specimen and asphalt layer, taking care not to destroy the asphalt layer so that its interface surface can be examined. BS EN 14692:2017EN 14692:2017 (E) 7 4.4.1.4 Check the condition of the sheet that was

37、removed from the part of the test specimen, and hold up to the light to detect any perforations due to compacting of the asphalt layer. 4.4.1.5 For bitumen sheets remove the binder from the reinforcement by extraction (for example with toluene as solvent). 4.4.1.6 Dry the reinforcement in an oven at

38、 (100 5) C for 30 min approximately, and hold up to the light to detect any perforations. 4.4.1.7 In case of perforations, test on the two remaining parts of the test specimen (see 4.4.1.2) the waterproofing complex (bitumen sheet and asphalt layer) for watertightness according to the test method de

39、scribed in Annex A. 4.4.2 Test specimen with sheet not bonded to the base specimen (Method 2) Separate the waterproofing sheet, and visually inspect its condition. If the visual inspection reveals perforations in the waterproofing sheet, the watertightness test need not be performed. If the visual i

40、nspection reveals no perforations, test the waterproofing sheet for watertightness according to EN 1928, Method B with a pressure of 100 kPa for 24 h. 4.5 Expression of results 4.5.1 Visual inspection test For Method 1: Report any perforation after the operations of 4.4.1. In case of no perforations

41、, express the resistance to compaction of an asphalt layer as “resistant”. For Method 2: Report any perforation after the operations of 4.4.2. In case of perforations, express the resistance to compaction of an asphalt layer as “not resistant”. 4.5.2 Watertightness test For Method 1: In case of perf

42、orations detected according to 4.4.1, express the resistance to compaction of an asphalt layer as “resistant” if no leak is detected when tested according to Annex A. For Method 2: Express the resistance to compaction as “resistant” if the waterproofing sheet does not leak when tested according to t

43、he method given in 4.4.2. 4.5.3 Precision of the test method No precision data are currently available. 4.6 Test report The test report shall include at least the following information: a) all details necessary to identify the product tested and identification of the whole waterproofing system inclu

46、ermination of watertightness for Method 1 A.1 General A.1.1 Purpose of the test The purpose of the test method is to determine the watertightness of test specimen according to Method 1 (4.1). A.1.2 Principle of the method The test consists of subjecting a specimen of the waterproofing system in a cl

47、osed cell to a specified water pressure and observing the absence of water transmission through the system. A.2 Equipment A.2.1 Apparatus, suitable for applying pressures up to 1 MPa in measuring cells in which the test specimens to be tested are placed (see an example of apparatus in Figure A.1). A

48、.3 Test specimens Obtain test specimens with a diameter of 150 mm and a maximum thickness of 70 mm by coring. After coring, heat the test specimens under a controlled temperature (4.4.1), and separate the complex at the waterproofing/concrete interface. A.4 Test procedure A.4.1 Installation of test

49、specimens Place the lower shells of the measuring cells and tins of hard bitumen (20/30 pen) in an oven at 140 C for at least 2 h. Remove the lower shells from the oven and place the test specimens in them. Pour the hot bitumen into the gap between the test specimen and the side of the test cell in order to ensure a perfect seal. After cooling, fit the cells with the top shell and connect to the apparatus (see Figure A.1).
