## Aggregate Testing Equipment Aggregate Crushing Value

Aggregate Crushing Value Test Step By Step Procedure The average crushing value in the different tests is the actual crushing value of aggregate important points to remember it is recommended that the crushing value of aggregate should be less than 30 if it is more than 30 then 10 finer aggregate is suggested to use the aggregate whose crushing value is less than 30 can be used for Aggregate Crushing Value Test Determine Aggregate Aggregate 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 Aggregate Crushing Value Test Significance Test The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the is sieve 236mm and the weight of the dried aggregate sample at least three samples should be tested from the same batch and average value to get accurate results Standard Of Crushing Value Of Coarse Aggregates For Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt pa mixture to determine the technical requirements of crushing value of coarse aggregate used in pa mixture steploading compression tests were conducted on the mixtures of pa13 and a control asphalt mixture ac13 respectively
