29、) compactor, gyratory compactor, or a vibratory compactor.This European Standard applies to bituminous mixtures, both those prepared in laboratory and those resulting sampled from plant produced mixtures. The results of the test method serve to supplement the results of mixture design.2 Normative re

34、cted (K when evaluated by gyratory compaction and k when evaluated by vibratory compaction)NOTE High values of K and k will indicate a mixture for which less compaction energy is required to obtain a given void content decrease.3.2compaction resistanceC, T resistance of an asphalt mixture to being c

36、n void content decrease.5BS EN 1269710:2017EN 12697-10:2017 (E)4 PrincipleThe bituminous mixture is compacted at a prescribed temperature with varying compaction energies using one of three optional types of compaction methods:a) impact compactionb) gyratory compactionc) vibratory compaction.Two met
37、hods of monitoring the compactability can be applied: Method 1: two or more specimen are compacted with different amounts of compaction energy and their densities are measured. Method 2: one specimen is used and its increase in density during the compaction process is determined from its decrease in
38、 thickness.The following Table 1 defines the compaction type to use depending of the compactness of tracking method and gives the clause of test procedure.Table 1 Compaction typeProcedure clause according to compaction methodimpact gyratory vibratoryCompaction of specimens with varied compaction ene
39、rgy 6.1.1 n. a. 6.3Measurement of specimen thickness during compaction 6.1.2 6.2 n. a.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
40、the number of gyrations and when the vibratory compactor is used, by the duration in seconds.A mathematical formula is derived from the experimental results, the parameters of which formula characterize the compactability of the bituminous mixture.5 Apparatus5.1 Impact compaction5.1.1 Marshall compa

All measurements shall have a limit deviation of 0,1 mm. Calculate the mean final thickness of the specimen from these fou
