Aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is: 2386 (part iv) – 1963. the apparatus used is cylindrical measure and plunger, compression testing machine, is sieves of sizes –, 10mm and procedure to determine aggregate crushing value i) the aggregates passing through
WhatsAppAggregate Crushing Value (ACV) and Ten Percent Fines Value .
These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration. 150mm Aggregate Crushing Value Apparatus.

Recycled Aggregate
Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.
