"Understanding Absolute Viscosity of Bitumen: VG Grades, Measurement, and Importance"

Key points about absolute viscosity of bitumen: Definition: It's the internal resistance of bitumen to flow. Measurement: Typically measured using a vacuum capillary viscometer at 60°C. Units: Poise (P) is a common unit. Importance: Viscosity affects how easily bitumen can be mixed, transported, and compacted. It's also a key factor in determining pavement performance at different temperatures. VG Bitumen: Viscosity Graded (VG) bitumen is classified based on its absolute viscosity at 60°C, with different grades (VG-10, VG-20, VG-30, VG-40) indicating different viscosity ranges.🔍 Dive deep into the viscous world of *bitumen* in our latest video! Discover everything you need to know about *absolute viscosity**, also known as dynamic viscosity—the crucial measure of a substance’s flow resistance due to internal friction. This essential property is instrumental in understanding and ensuring optimal performance for asphalt applications. Measuring at **60°C* using a vacuum capillary viscometer, we showcase VG-20 bitumen's dynamic viscosity, typically ranging from **1600 to 2400 poise**. 🌡️ Whether you're a civil engineer or simply curious about the science behind materials, this video is packed with valuable insights!
