This percentage is known as a crushing value of aggregate. This percentage should not exceed 30% of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%.

6. Impact, 10% Fines & Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries, e.g., Australia and New Zealand, only use the latter test.

Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.
