Aggregate Crushing Value Test Civil Planets

Significance of Aggregate Crushing Value Test The crushing value test is conducted on aggregates that are used for the construction of roads Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load The road is subjected to motion pressure continuouslyThis test is repeated once or twice and the average crushing value of the aggregate is determined 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 aggregateAggregate crushing value test Civil ConceptAggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined The average crushing value in the different tests is the actual crushing value of aggregate Important points to remember 1It is recommended that the crushing value ofAggregate Crushing Value Test Civil Concept
