12/9/2023 0 Comments Absolute viscosity unitHeating of the bath is done electrically. Water bath: It is cylindrical in shape and is made of a copper sheet. If the upper rim of the orifice is not perfectly circular, then the valve cannot be properly seated.ģ. The extension is drilled and polished to form an orifice of 10 mm diameter. The plate helps in the drainage of tar after use. It has centrally-located extensions made up of same material and cylindrical in shape. While a phosphor-bronze plate which is circular in shape is screwed into the cylinder and made conical. The collar helps in supporting the cup in the sleeve of the water bath. It has an external brass collar at the upper open end of the cylindrical cup. Cup: It is also known as a 10-mm cup and has a specified orifice and valve. Tar viscometer is used for determining industrial viscosity of bitumen whose parts are discussed below: Tar ViscometerĢ. Apparatusįollowing apparatus are used in the viscosity of bitumen test-ġ. Industrial viscosity: It is the property of a fluid by virtue of which it is able to resist the flow caused by internal friction. Important Terms related to Industrial Viscosity Test of Bitumen The industrial viscosity of bitumen is measured by determining the time taken by 50 cm 3 volume of material to flow from a cup through a specified orifice in standard conditions of temperature and a specified temperature. To determine the industrial viscosity of bitumen, road tar, and cutback bitumen’s. Therefore, it is essential to select a binder with appropriate viscosity so that it can form a uniform coat and fill up the voids between aggregates effectively. Workability will also be affected of a highly viscous bitumen specimen. It will not help in the binding of the particles which is its primary purpose.Ī highly viscous binder will restrict the flow, thus it restricts the ability of binder to spread and fill up the voids between the aggregates during pavement construction.Īlso, it will require more efforts comparatively, and there is also a possibility of it forming a heterogeneous mix. If the bituminous binder used in the pavement has much lower viscosity value, then it will act as a lubricant only. It ensures the quality of the bitumen used as a binder by giving a measure of fluidity at a particular temperature. Viscosity measures the degree of fluidity of the bitumen sample. Viscosity test of the bitumen sample is one of the important tests on bitumen to be conducted before road construction.

View all measurement unit conversion calculators on the same page (may not work with all browsers requires Iframe). The calculators require that your browser has java script enabled. Values lower than 0.001 will be displayed in the e-format e.g. Values of 10 000 or greater will be displayed in the e-format e.g. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). All results shown will be equivalent values. To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. Dynamic viscosity is the tangential force per unit area (shear or tangential stress) required to move one horizontal plane with respect to the other at unit velocity when maintained a unit distance apart by the fluid (velocity gradient or rate of shear).ĬONVERSION CALCULATORS Convert between Different Units of Measurement Index of Unit Converters Sorry, your browser does not support JavaScript, which is needed to run this calculatorĭynamic Viscosity (absolute viscosity, coefficient of viscosity) Definition:Ī measure of the resistance to flow of a fluid under an applied force.
