Aggregate Impact Value Calculator, Test on course and Fine

Why to test Aggregate Impact Value? Toughness is the property of a material to resist impact. Due to traffic loads the road stone are subjected to the pounding action of impact and there is possibility of breaking into smaller pieces. The road stone should therefore be tough enough to resists fracture under impact.

RELATIONSHIP BETWEEN AGGREGATE CRUSHING VALUE (ACV) AND TEN

It is used to determine the crushing value of a given road aggregate also it is used to assess ... material to be used for wearing course (top part of ... 2.2.1 Aggregate Crushing Value (ACV) Test:

Aggregate - AfriSam

The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the flexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality. Normal values for ACV range from 14 to 30%, and for
