A contractor needs 214 yd' of aggregate base material for a highway construction project. It will be compacted to a dry unit weight of 130 lb/ft'. This material is available in a stockpile at a local material supply yard, but is sold by the ton, not by the cubic yard. The moisture content of the stockpile is 7.0%. (a) How many tons of aggregate base material should the contractor purchase to have exactly the correct volume of compacted material? (b) The contractor purchased the material per the computation in part (a), and it exactly met the needs at the project site. An intense rainstorm occurred the following week, which delayed further construction and raised the moisture content of the stockpile to 19.0%. Now, the contractor needs to prepare another identical section of aggregate base and is ordering the same number of tons as before. How many cubic yards of compacted aggregate base will be produced from this second shipment? How will it compare with the first shipment? Explain.
