temperature of the oven be? (C29) Answer: 230°F (+/- 10°F)
◉ When is an aggregate sample considered at constant mass? (C29)
Answer: When the 2 sample weights taken an hour apart is less than
.1%
◉ What is the formula for Bulk Density? (C29) Answer: (mass of agg.
and measure - mass of measure) /volume of measure

Answer: Greater than 1.5", but no greater than 5"
, ◉ What is the formula for void content? (C29) Answer: 100[(bulk
specific gravity X density of water) - Bulk Density of agg./ bulk
specific gravity X density of water
