and also asphalt pavements. Aggregate is made of mixing the sand, gravel, crushed aggregate, or other materials has been proven that aggregate must have suitable strength and durability to able the impact acting on it in term of moving or static load. We blow the Aggregate Impact Machine 15 times to replicate the sudden impact and moving loads.
Aggregate Crushing Value Test – Procedure, Result
The aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed aggregate sample passed through 2.36 mm IS Sieve.
