· The aggregate impact value (AIV) is B AIV = × 100 (%) . . . (1) ARESULTSAn average is taken of the two tests and the result is recorded to the nearestwhole number as the Aggregate Impact AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose. For weak aggregates, the required load ...

Malaysian Test Method On Aggregates Crushing Value. The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS .
Light Impact Value has appliions for recreation turf hardness evaluation, where the condition of the surface affects ball bounce characteristics, the performance or injury potential to participants, and where more sensitivity compared to the standard hammer is required or an imprint left by the kg (10 lbm) hammer or other test methods is undesirable, such as on a golf putting green.
iv. The 10% fines value when tested in accordance with MS 30 shall be not less than 30 kN. v. The sand equivalent of aggregate fraction passing the No. 4 ( mm) sieve when tested in accordance with ASTM D 2419 shall be not less than 45%. Construction Methods
AGGREGATE CRUSHING VALUE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate 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.
