Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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

3.2 Crushing test A laboratory jaw crusher (figure 1) was used in the crushing experiments. Firstly, block samples were crushed using a hand hammer to small sizes which were suitable for the crusher and charged to the crusher with a wide outlet gap. A charging size range of 19⋅0–9⋅52 mm for the crusher was selected.

aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes, Gourley and Ohikere [5] recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess aggregate durability. The Micro-Deval abrasion test was developed in France during the 1960''s.
