Aggregate Crushing Value Test Procedure And Result

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations when the aggregate value 30 or higher the result may be a mistake and in such cases the ten percent fines value should be determined .

Quality Assurance For Aggregates

The aggregate crushing value should not exceed 45 for aggregate used for concrete other than for wearing surfaces and 30 for concrete for wearing surfaces such as runways roads for pavements. Aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact As an alternative to

Los Angeles Abrasion Pavement Interactive

The Los Angeles L.A. abrasion test Figure 1 is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing degradation and disintegration in order to produce a high quality HMA.

Crushing Value Test Of Aggregates Importance Procedure

Jul 18 2021 Coarse aggregate crushing value is the percentage by weight of the crushed material under standardised load and condition. The crushing value indicates the strength of aggregates. The aggregates used for quality pavement should be strong enough to withstand the crushing under roller and traffic loads i.e. Low crushing value.
