Bullas and West 4 reported the aggregate impact value did not, but the 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 Effect Of Aggregate Properties On Concrete

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm retained on a No. 4 sieve, while fine aggregate is less than 4.75 mm passing the No. 4 sieve. The compressive aggregate strength is an important factor in the selection of aggregate.
