Aggregate Tests

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. The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing value.
