Aggregate Tests
Crushing test – provides an indication of aggregate resistance to crushing under an applied crushing load. The test requires samples of the aggregate to be subjected to standard load crushing conditions. Multiple layers of presieved materials are tamped 25 times before a 40-ton load is applied at a rate of 4 tons per minute.
