REPRODUCIBILITY OF RESULTS IN THE AGGREGATE IMPACT TEST. THE INFLEUCNE OF NON-GEOLOGICAL FACTORS

The article discusses the problem of obtaining consistent test results when evaluating aggregates; to accurately represent the performance of an aggregate, it is thought desirable to use an appropriate strength test in conjunction with the polished-stone value test. Of several tests to assess aggregate strength, the impact test is said to be the simplest, measuring resistance to shock loads. In order to amplify this test, impact value residue (IVR) has been introduced by the authors; it concerns the proportion of material remaining within the original aggregate sample size after testing. Details are given of various ways in which a number of non-geological factors such as adjustment and sitting of testing apparatus can cause variation in impact test values. /TRRL/
