Thoroughly mix the aggregate sample and reduce it to an amount suitable for testing, using a sample splitter or by quartering. The minimum sample size should be as follows: Minimum Mass, kg Fine aggregate with at least 95% passing 2.36-mm sieve 0.1 Fine aggregate with at least 85% passing 4.75-mm sieve 0.5 Coarse aggregate with a nominal maximum size of 9.5 mm 1 Coarse aggregate of a nominal maximum size of 12.5 mm 2 Coarse aggregate of a nominal maximum size of 19.0 mm Coarse aggregate of a nominal maximum size of 25.0 mm 10 Coarse aggregate of a nominal maximum size of 37.5 mm 15

If needed assume the unit weight of water to be 62.4 lb/ft3 a) A HMAC sample has the following volumetric properties (i) VMA = 0.1865 ft3and (ii)Volume of air = 0.0452 ft3 Compute %VFA.  b) A HMAC sample has 140 lbs of aggregate with a bulk specific gravity of 2.65 and aneffective specific gravity of 2.71. Based on this information the volume of the absorbedasphalt is ________________ft3A compacted sample of hot mix asphalt concrete sample has a unit weight of 135 lb/ft3.c) The sample has an asphalt content of 5% (by weight). Assume no absorbed asphalt.The bulk specific gravity of the aggregate is 2.65, and specific gravity for the asphaltcement is 1.05. Based on this information compute VMA for this mixture.
