Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more ...

NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of 'aggregate crushing value' 30 or higher, the result may be anomalous, and in such cases the 'ten percent fines value' should be determined instead. ...

Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.

Obviously, the test result indicated in Table 3 shows that the aggregate crushing value was 34.01%, 19.70%, and 10.79% for Scoria gravel, Marble Waste Aggregate, and Crushed Stone Aggregate respectively. Therefore, scoria gravel and marble waste aggregate do not satisfy the minimum requirement for base course materials in dry conditions.
