Asphalt binder viscosity is essential in both the ease of construction and durability of asphalt pavements. This article explores the basics of viscosity measurement, and details two key standards for viscosity testing: ASTM D4402 and AASHTO T316.
There are various types of viscometers. For example, Ostwald's famous capillary tube viscometer, falling body viscometer, rotor type viscometer, etc. We will introduce the features and types of each viscometer.
Do you know what a viscosity is? This article presents basic information about viscosity in an easy-to-understand manner. We also introduce units such as cps and dPa·s, which are often used to measure viscosity.
Viscosity is greatly affected by temperature and time. We will introduce how much the viscosity changes and how it changes depending on the two factors.
