Dec 19, 2019 If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

4. CRUSHING RESISTANCE This test indicates the ease of processing (s trength) of the aggregate and the likelihood of attrition. Although materials which have a crushing resistance less than 130 kN cannot be classified as M/4 basecourse this does not necessarily preclude their use where stronger aggregates are not available.
