Classification, properties and extraction of Aggregates

Jan 28 2017 Road Aggregate: By volume aggregate generally account for 92 to 96 of bituminous concrete. Road aggregate are the non-active inert material used to provide mass to the base and sub-base courses. Road aggregate should have high strength to bear the traffic load. Road aggregates must have higher impact value to withstand the Tyre impact phenomenon.
