Which statement correctly describes Cutback Asphalt with its property?

• A. A paving asphalt liquefied by blending with petroleum solvents
• B. A mixture of asphaltic cement, water & emulsifying agent
• C. Cut with petroleum solvents
• D. Prime coat, dust control

Answer: (C)

Cutback asphalt is asphalt cement that has been diluted with volatile petroleum solvents to lower its viscosity, making it easier to pump, spread, or spray at lower temperatures. The defining property is this addition of petroleum solvents to the asphalt cement, which reduces viscosity and allows workable application before the solvent eventually evaporates and the asphalt cures. The other descriptions don’t pinpoint this dilution process: one refers to emulsified asphalt (which uses water and an emulsifier, not solvents), and another describes a use (prime coat, dust control) rather than the material’s defining treatment.
