PROPERTIES AND TESTING OF AGGREGATES FOR PAVEMENT WORKS
Aggregate crushing value gives the Crushing strength of aggregate up to which it can bear the load without fail. To conduct crushing strength test we need compression testing machine, cylindrical measure, plunger and Isa sieves. First sieve the sample aggregate, aggregate passing 12.5mm sieve and retaining 10mm sieve is oven dries at 100-110 o ...
Pavement materials Aggregates
One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing …

How to Determine the Aggregate Crushing Strength Value in
Apr 26, 2018 Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.
Aggregate Crushing Value Test Determine Aggregate
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 economical performance.
