contractor needs 403 m3 of aggregate material for a highway construction project. The required dry unit weight of the compacted fill is 20.82 kN/m3 . The aggregate material is available at a local supply yard and is sold by measuring in tons and not by volume. The moisture content of the stock is 7%. The cost of the aggregate material per ton is 60. B.1.1 Determine the amount of water present in the aggregate stock of the local supply yard. B.1.2 Determine the amount of aggregate material the contractor should purchase in tons to have exactly the correct volume of compacted material. B.1.3 Estimate the total cost the contractor has to bear for the purchase of the material.
