24、75:2004 and prEN 14695:2003 apply. 4 Test methods 4.1 Principle The test consists of compacting an asphalt layer of a determined composition on a bitumen 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

25、the base specimen; Method 2: A de-bonding interface is laid between the base specimen and the sheet and between the sheet and the asphalt layer. After compacting of the test specimen, the bitumen sheet is recovered for observation of its condition and any perforations. Depending on the results of th

26、e observations, the watertightness of the recovered bitumen sheet should be checked. EN 14692:2005 (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 (

27、without fresh supply), 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

28、 of the test specimen is 600 mm x 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 bitumen sheet, and on the upper surface of the bitumen sheet to prevent the asphalt layer adhering to it. For the interfa

29、ce between the base specimen and the bitumen sheet, use one non-woven glass fibre sheet of (70 5) g/m. For the interface between the bitumen sheet and the asphalt layer mix, use two non-woven glass fibre sheets of (70 5) g/m. The size of the test specimen is 300 mm x 300 mm. 4.3.4 Asphalt layer, com

30、paction 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 sawing the test specimen, prepare

31、d 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. EN 14692:2005 (E) 7 4.4 Procedure 4.4.1 Test spe

32、cimen 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 specimen in an

33、 oven at (100 5) C for (120 5) min. 4.4.1.3 Separate the bitumen 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. 4.4.1.4 Check the condition of the bitumen sheet that was removed from the part of the

34、 test specimen, and hold up to the light to detect any perforations due to compacting of the asphalt layer. 4.4.1.5 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 (100 5) C for 30 min approximately, and hold u

35、p 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 described in normative Annex A. 4.4.2 Test specim

36、en with sheet not bonded to the base specimen (Method 2) Separate the bitumen sheet, and visually inspect its condition. If the visual inspection reveals perforations in the bitumen sheet, the watertightness test need not be performed. If the visual inspection reveals no perforations in the bitumen

37、sheet, test the bitumen sheet for watertightness according to EN 1928, Method A 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, express the resistance to compac

38、tion 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 perforations detected according to 4.4

39、.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 bitumen sheet does not leak when tested according to the method given in 4.4.2. 4.5.3 Precisio

40、n of the test method No precision data is currently available. EN 14692:2005 (E) 8 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 including asphalt layer an

43、od 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 closed cell to a specified water pressu

44、re 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.3 Test specimens Obtain test specime

45、ns 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 specimens Place the lower shells of t

46、he 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

47、 cooling, fit the cells with the top shell and connect to the apparatus (see Figure A.1).
