38、 vertical and horizontal permeability of cylindrical specimens of bituminous mixtures with interconnecting voids. The standard applies to specimens cored out of the road, specimens from laboratory made slabs or laboratory specimens prepared with a compaction device provided the thickness of the spec
39、imen is not less than twice the nominal maximum particle size of the aggregate in the mixture. The nominal diameter of specimens should be either 100 mm or 150 mm unless the nominal maximum particle size of the aggregate size exceeds 22 mm, when the nominal diameter is 150 mm. 2 Normative references

41、97-29, Bituminous mixtures Test methods for hot mix asphalt Part 29: Determination of the dimensions of a bituminous specimen 3 Principle A column of water with a constant height is applied to a cylindrical specimen and is allowed to permeate through the specimen for a controlled time in either a ve
42、rtical or horizontal direction depending upon the parameter being measured. The resultant flow rate of the water Qvor Qhis a calculated measure of the permeability value Kvor Kh. The test is carried out at ambient temperature. NOTE When the void content of the same specimen is determined, the relati
43、onship between permeability and void content can be established. 4 Vertical permeability 4.1 General In this method, only the water flow in a vertical direction through the specimen is measured. 4.2 Apparatus for vertical permeability 4.2.1 Apparatus as shown in Figure 1. The dimensions shall be suc
44、h so as to ensure the water column height is (300 1) mm. The external diameter of the tube and any fittings shall be such that no water can flow between the wall of the tube and the specimen when in place; the thickness of the tube shall be sufficient to ensure it retains its shape but shall not be
45、more than 5 mm. NOTE 1 The external diameter of the tube should generally be greater than the diameter of the specimen by up to 5 mm. NOTE 2 A suitable rubber cuff that fits snugly around the tube and sample is one method to ensure that no water can flow between the two. Another approach that could
46、be used is to attach the plastic tube with duck tape to the specimen. 4.2.2 A balance with suitable capacity and capable of weighing to the nearest 0,5 g. BS EN 12697-19:2012EN 12697-19:2012 (E) 7 4.3 Procedure 4.3.1 Determine the dimensions of the specimen, to the nearest millimetre, according to E
47、N 12697-29. The thickness shall be greater than 25 % of the diameter and greater than twice the nominal maximum aggregate size of the mixture. 4.3.2 If the specimen is trimmed by saw cutting, it shall be cleaned prior to testing, to prevent restriction of the water flow. 4.3.3 The test shall be carr
48、ied out at ambient temperature within the ranges of 15 C to 25 C and shall be monitored and recorded. Place the specimen in a rubber cuff. Insert a plastic tube in the cuff and place it on top of the specimen. Carefully inflate the rubber cuff with air to at least 50 kPa, so that it presses firmly around the wall of the specimen to prevent leakage of water along the wall. A seal needs to be ensured between the cuff and the tube.
