Page 6 EN 12697-1 3:2000 1 Scope This European Standard describes a test method for measuring the temperature of hot bituminous mixtures after mixin
33、g and during storage, transportation and laying. This standard does not include the use of non-contact temperature-measuring devices. 2 Principle A probe attached to a temperature measuring device is preheated before the temperature at stated depths in a number of locations is measured while the asp
34、halt is in one of several different places. The average is then calculated. 3 Apparatus 3.1 General The temperature measuring device shall measure the temperature in intervals of 5 OC or smaller with an accuracy of f 2 OC and be fitted with a suitable probe of which the response time is known for th
35、e temperature interval which is to be measured. The temperature measuring device and probe shall be suitable for the use in that location where the temperature is to be measured. NOTE 1 Several types of temperature measuring devices are suitable, e.g. electronic thermometers using thermocouples or t
36、hermistors or bimetallic rotary thermometers. Thermometers of the latter type, although cheapest, are possibly least satisfactory owing to their comparative flimsiness, slow response time and need for frequent recalibration. More robust models are available but robustness is associated with lengthen
37、ed response time. NOTE 2 With the electronic type, the heat-sensing element is very small and is normally mounted in the tip of the probe, and therefore one probe can be used for measuring temperatures of both bulk and as laid material. Thermocouple probes available cover a large temperature range,
38、e.g. of 400 OC, while those using thermistors are sufficiently accurate only over a limited range, e.g. of 1 O0 OC. NOTE 3 The thermal capacity of the temperature measuring device should be as small as possible, consistent with adequate robustness, to minimize the time required to obtain a reliable
39、reading. 3.2 Devices for measuring the temperature of material in a lorry or in a heap The probe of the temperature-measuring device shall have a minimum length of 300 mm, with the sensing element positioned close to the end. 3.3 Devices for measuring the temperature of material after it has been la
40、id and before or during rolling a The temperature-measuring device shall have a temperature sensitive element small enough to be completely buried within the bituminous material, which has been laid. a Page 7 EN 12697-1 32000 o4 Procedure 4.1 Conditioning of instrument Allow the probe to the tempera
41、ture-measuring device to heat up to the appropriate temperature of the material by placing it in one position and then quickly moving it to another position to obtain the first measurement. NOTE The insertion of a cold probe of relatively high thermal capacity will remove sufficient heat from the ma
42、terial to give a low temperature reading because of the low thermal capacity and conductivity of bituminous mixtures. 4.2 Measurements of temperature in a lorry Insert the probe into the lorry - load of material to a depth of at least 1 O0 mm. Take at least four measurements at evenly spaced interva
43、ls along each side of the lorry and at least 500 mm from the edges of the load. Calculate the result as the average of all the readings. 4.3 Measurements of temperature of laid materials Take at least four measurements of the material with the temperature sensitive element as close as possible to th
44、e mid-depth of the layer. Calculate the result as the average of all the read i ngs. NOTE When measuring the temperature of asphalt to which chippings are applied, because of the short time normally available between laying the asphalt and the chippings being applied or commencement of the rolling i
45、t is unlikely that four measurements can be taken in a small area using a bimetallic thermometer because of its response time. If necessary, more than one such thermometer should be used to avoid delays in rolling. Alternatively, an electronic type of temperature measuring device should be used to o
46、btain quicker readings. 4.4 Measurements of temperature in a heap Insert the probe into the material to a depth of at least 1 O0 mm. Take at least four measurements at intervals around the accessible perimeter and at least 300 mm from the base. Calculate the result as the average of all the readings
47、. NOTE A heap is assumed to be on the ground and not within equipment such as the paver hopper. There are additional inherent dangers in measuring the temperature of a bituminous mixture in a paver hopper. o 5 Testreport 5.1 Information The test report shall include the following information as appr
48、opriate: a) Date, time and place of testing; b) load number; c) site of measurement (in lorry, laid or heap material); d) type and identifying number of the temperature measuring device used; Page 8 EN 12697-1 312000 e) specification of the material; f) average result to the nearest 5 OC; g) name of
49、 person performing the test; h) the number and date of this European Standard. 5.2 Optional information If required, the test report shall also include additional optional information such as the following: a) Name of project; b) name of supplier and source of material; c) date of production of material. 6 Precision There is no precision statement for any of these devices.
