WhatsAppGet PriceGet A QuoteAggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
WhatsAppGet PriceGet A QuoteAggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.
WhatsAppGet PriceGet A QuoteThe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS
WhatsAppGet PriceGet A QuoteCrushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.

The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample
WhatsAppGet PriceGet A QuoteIn current Chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% . So, the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%/1.48 = 17.6%.

Which one is better ~nd why? What are the applications of aggregate crushing test? What are the recommended maximum values of aggregate crushing value for the aggregates to be used
WhatsAppGet PriceGet A QuoteThe crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads. The standard aggregate crushing test is made on aggregate passing 12.5mm IS sieve and retained on 10 mm IS sieve. Procedure. About 6.5 Kg material consisting of aggregates passing 12.5mm IS sieve and retained on 10mm sieve is
WhatsAppGet PriceGet A Quote“Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test” Aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure.
