May 17, 2019  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

AGGREGATE TOUGHNESS/ ABRASION RESISTANCE AND

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.

In 1973, Ted Ondrick Co. had the first drum mix asphalt plant in Massachusetts. As the recycling concept developed, Ted Ondrick Co. became a resource to implement regional recycling by using recycled asphalt (RAP) in 1976. This allowed the community to recycle, rather than landfill – asphalt, concrete, and soil materials.
