PROPERTIES AND TESTING OF AGGREGATES FOR …

Aggregates plays vital role in the construction of pavement. They have great capability of load transfer to the Subgrade soil. Aggregates have different properties which are tested individually with different types of tests for the construction of pavement. Aggregate should qualify all the tests conducted to give better results after construction.
