This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.

Aggregate Crushing Value (ACV) This test is used to find the strength of the coarse aggregate and indicates the resistance to crushing under a gradually applied crushing load. It is measured as the percentage of aggregates passing through 2.36 mm IS sieve after the specimen subjected to a compressive load of 40 tonnes at the rate of 4 …

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 ...

The 10% fines value is a metric that gauges the ability of aggregates to withstand crushing under loading, and it is applicable to both weak and strong aggregates. Fine aggregates are those that pass through a 2.36mm sieve. This test seeks to determine the amount of force required to produce 10% of fine values, which is expressed as the …

The Polished Stone Value (PSV) Test is a method used to determine the resistance of an aggregate to polishing and its ability to provide skid resistance on road surfaces. The test method is outlined in detail in BS 812-114, and EN 1097-8, and a copy of the document is necessary to perform the test correctly.
