standard impacts from a dropping weight. The impacts break the aggregate to a degree which is dependent on the aggregate’s impact resistance. This degree is assessed by a sieving test on the impacted specimen and is taken as the aggregate impact value. 7.6.3 Sampling. The sample used for this test shall be taken in accordance with Chapter 2.
