In effect, the test is an indirect determination of high temperature viscosity and low temperature stiffness. Significance of viscosity test. 1- Too viscous bitumen would result in inadequate and non-uniform coating of the aggregates. ABSOLUTE VISCOSITY TEST OF BITUMEN Reference. 10.1 Bitumen Penetration Test 10.1.1 General requirements 10.1.1.1 Scope. VISCOSITY TEST FOR BITUMEN PRESENTED BY:AMRIT PANDIT ACEM/069/A/005 KATHMANDU, NEPAL 2. Objective • To become familiar with the term viscosity, its influence and effects, its techniques and application in the field of engineering especially for design of the road pavements. General description of viscosity grade bitumen (Asphalt) Traditionally, paving bitumen have been specified in terms of their penetration, but the measurement of viscosity provides a more accurate method of specifying binder consistency and a more effective method of determining the temperature susceptibility of the bitumen. The following testing equipment is needed to measure absolute viscosity of viscosity graded paving bitumen (IS:73-2006) at 60 C in accordance with IS:1206 (Part 2) (similar to ASTM D 2171), which uses a vacuum … The two factors that define the viscosity of bitumen are: Chemical Composition of Bitumen Structure of Bitumen […] IS: 1206 (Part 2) – Method for Testing Tar and Bitumen Materials: Determination of Absolute Viscosity Test Equipment. Under the action of force, the fluid reflects higher resistance when the viscosity is high. viscosity test of bitumen 29 May 2018 10 Sep 2018 VISCOSITY: Its defined as fluid property of the material as resistance to flow AIM: To determine the viscosity of bitumen by tar viscometer as per IS: 1206 (Part 2) APPARATUS: Tar… This is a basic test for determining the grades of bitumen. Viscosity Grade Bitumen. The scope of this is to provide a method for determining the consistency of semi-solid Introduction to Viscosity and Rheology of Bituminous Materials The resistance of a liquid in flowing is defined as the viscosity of that fluid. Kinematic and Dynamic viscosity thermometers 82-B0116/40 Kinematic viscosity thermometer, range 58.5 to 61.5°C, type ASTM 47C 82-B0116/45 Kinematic viscosity … 2- Very low viscosity would again result in inadequate coating as the bitumen will tend to bleed. 3- Therefore viscosity at 135oC is a true reflection of the quality of bond that is likely to be formed with the aggregate. Viscosity test of bitumen 1.
