The hot mix calculator uses a standard density of how many pounds per cubic foot?

• A. 150
• B. 100
• C. 200
• D. 250

Answer: (A)

Hot mix calculators convert volume to weight using a standard unit weight for the material. For hot mix asphalt, the bulk density of compacted material is typically around 145–150 pounds per cubic foot, and 150 pounds per cubic foot is the standard value used in many calculators. This means one cubic foot of HMA weighs about 150 pounds; a cubic yard (27 ft³) would weigh about 4,050 pounds (roughly 2.0 tons). In practice, actual density can vary with asphalt content, aggregate type, degree of compaction, and moisture, but 150 pounds per cubic foot is the common standard used in the calculator.
