Determine The Crushing Value Of Coarse Aggregate

Aggregate Crushing Value Test The objective of this test is to: Determine the aggregate crushing value of coarse aggregate; Assess suitability of coarse aggregates for use in different types of road; Apparatus A steel cylinder 15 cm diameter with plunger and base plate A straight metal tamping rod 16mm diameter and 45 to 60cm long rounded at one end
The aggregate crushing value for cement concrete pavement shall not exceed 30% The aggregate crushing value for wearing surfaces shall not exceed 45% PURPOSE OF TEST: The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load
Procedure to determine Aggregate Crushing Value i) The aggregates passing through 125mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod
