30、ty or void content and the compaction energy applied to it, using an impact (Marshall) compactor, gyratory compactor, or a vibratory compactor. This European Standard applies to hot bituminous mixtures (both those prepared in laboratory and those resulting sampled from plant produced mixtures), with
31、 D not larger than 31,5 mm in accordance with prEN 13043 for the impact and gyratory compactors, and 40 mm for the vibratory compactor. The results of the test method serve to supplement the results of mixture design. 2 Normative references This European Standard incorporates, by dated or undated re

37、ard, the following terms and definitions apply. 3.1 soluble binder percentage by mass of extractable binder in an anhydrous sample determined by extracting the binder from the sample NOTE Extraction may be followed by binder recovery. 3.2 insoluble binder content percentage by mass of binder that ad
38、heres to the aggregate particles after extractionEN 12697-10:2001 (E) 6 3.3 precision closeness of agreement between independent test results obtained under stipulated conditions NOTE 1 Precision depends only on the distribution of random errors and does not relate to the true value or the specified
39、 value. NOTE 2 The measure of precision is usually expressed in terms of imprecision and computed as a standard deviation of the test results. Less precision is indicated by a larger standard deviation. NOTE 3 “Independent test results” means results obtained in a manner not influenced by any previo
40、us result on the same or similar test sample. Quantitative measures of precision depend critically on the stipulated conditions. Repeatability and reproducibility conditions are particular sets of extreme conditions. 3.4 repeatability precision under repeatability conditions 3.5 repeatability condit

43、the same method on identical test items in different laboratories with different operators using different equipment 3.9 reproducibility limit value less than or equal to which the absolute difference between two test results obtained under reproducibility conditions may be expected to be with a pro
44、bability of 95 % NOTE The symbol used for reproducibility limit is R . 3.10 single test result value obtained by applying the standard test method fully, once to a single specimen may be the mean of two or more observations or the result of a calculation from a set of observations as specified by th
45、e standard test method 4 Principle The bituminous mixture is compacted at a prescribed temperature with varying compaction energies. One of two methods is used. In the first method two or more specimen are compacted with different amounts of compaction energy and their densities are measured. In the
46、 second method one specimen is used and its increase in density is determined after each stage of its compaction from its decrease in thickness. NOTE For impact compaction, both methods can be used. For gyratory compaction, the second method only is used. For vibratory compaction, the first method o
47、nly is used.EN 12697-10:2001 (E) 7 A graph is drawn of density (or voids content) against compaction energy. When the impact compaction is used, the compaction energy is characterized by the number of blows, when the gyratory compaction is used, by the number of gyrations and when the vibratory comp
48、actor is used, by the duration in seconds. A mathematical equation is derived from the experimental results, the parameters of which equation characterize the compactibility of the bituminous mixture. 5 Apparatus 5.1 Impact compaction 5.1.1 Different specimen for each level of compaction energy, recording increases in density 5.1.1.1 Marshall compactor in accordance with prEN 12697-30. 5.1.2 One specimen for all levels of compaction energy, recording decreases in thickness 5.1.2.1 Marshall compactor in accordance with prEN 12697-30. 5.1.2.2 Measuring device for automatically recording the th
