WebThe specific gravity of aggregate is determined along with the water absorption as specified in IS 2386 part III 1963. Sizes of Coarse aggregate: Uses of Coarse Aggregates: They are also used in the preparation of breaking moisture under slabs and vapor barriers. Also, they are part of base preparation for driveways and roadways. WebV t = total volume of the mixture Example: A compacted asphalt concrete specimen contains 5% asphalt binder (specific gravity = 1.023) by weight of total mix, and aggregate with specific gravity of 2.755. The bulk density of the specimen is 2.441 kg/m 3. Ignoring absorption, compute VTM, VMA and VFA.
