AC10, AC20, and AC30 are commonly used grades of asphalt cement, also referred to as AC10 asphalt, AC20 asphalt, and AC30 asphalt. These grades are classified based on their absolute viscosity measured at 60 °C in units of 100 poises. For instance, the viscosity of AC10 bitumen is 10 × 100, equaling 1000 poise (100 Pa·s).
