Bitumen in bitumenska veziva - Določanje dinamične viskoznosti bitumenskih veziv z uporabo rotacijskega viskozimetra

Ta evropski standard določa metodo za opredelitev dinamične viskoznosti različnih bitumenskih veziv: modificiranih in nemodificiranih bitumenskih veziv, bitumenskih emulzij ter rezanih in fluksiranih bitumenskih veziv s pomočjo koaksialnega viskozimetra.
Navedene so standardne temperature nanašanja, čeprav je dinamična viskoznost mogoče meriti tudi pri drugih temperaturah, če je to potrebno. Tudi viskoznost je navedena pri standardnih strižni hitrosti, čeprav se po potrebi lahko izvedejo dodatni ukrepi pri različnih strižnih hitrostih.

«2), kilogram per metre per square second

«1 „ s «2) or Pascal (Pa). 3.2 shear rate velocity gradient in a flowing fluid perpendicular to the stress Note 1 to entry: Shear rate is expressed in units per second (s «1). Note 2 to entry: The shear rate calculation depends upon the viscometer geometry. This should be mentioned by the viscometer manufacturer. SIST EN 13302:2018

EN 13302:2018 (E) 5 3.3 dynamic viscosity ratio between the applied shear stress and the shear rate Note 1 to entry: frequently used sub-unit. Note 2 to entry: Dynamic viscosity is the measurement of the resistance to flow of a liquid. 3.4 Newtonian fluid fluid having a viscosity that is independent of the shear rate Note 1 to entry: The ratio of the shear stress to the shear rate is the viscosity of the fluid. If this ratio is not constant the liquid is non-Newtonian and many fluids exhibit both Newtonian and non-Newtonian behaviour, depending on the temperature and the shear rate. 3.5 apparent viscosity term used to characterise the resistance to flow of a Newtonian or non-Newtonian fluid 3.6 form factor specific factor or factors to be applied for the individual equipment in order to obtain the actual viscosity from the readings, mainly due to the geometry of the apparatus 4 Principle The torque applied to a spindle (e.g. a cylinder) rotating in a special sample container containing the test sample, measures the relative resistance of the spindle to rotation and provides a measure of the dynamic viscosity of the sample. It may be necessary to apply a form factor to yield the actual dynamic viscosity at the test temperature. Some bituminous materials may exhibit non-Newtonian behaviour under the conditions of this method. Since non-Newtonian viscosity values are not unique material properties, but reflect the behaviour of the fluid and the measurement system, it should be recognized that measurements made by this method may not always predict performance under the conditions of use. Comparisons between non-Newtonian viscosities should be made only for measurements under similar conditions of shear stress and shear rate. Unlike paving grade bitumen, polymer modified bitumens (PMBs) do not show a straight line on the Heukelom diagram [2]. This implies that, in order to obtain information about the temperature susceptibility of PMBs, viscosity should be measured at different temperatures. SIST EN 13302:2018

EN 13302:2018 (E) 6 5 Apparatus Usual laboratory equipment, together with the following: 5.1 Rotating spindle viscometer, dynamic viscosity measurements with rotational viscometers on the bituminous products addressed by this standard may cover wide ranges of shear rates and viscosities: — Range of shear rate:

1 s «1 to 104 s «1 — Range of dynamic viscosities:
10 «2 Pa „ s to

s r6 Pa „ s In order to cover all product types mentioned in the Scope (Clause 1), under the most usual test conditions, this standard requires rotational viscometer(s) with sample containers and rotating spindles allowing following minimum capabilities: — Range of shear rate:

1 s «1 to 200 s «1 — Range of dynamic viscosities:
10 «2 Pa „ s to

s r3 Pa „ s NOTE 1 For rotating cylinders, the following conditions give an indication of correct measuring geometry: — Ratio of the radius: R2/R1

· 1,1 (reference to Figure 1); — Difference between the radius R2 – R1 = 1 mm to 6 mm. NOTE 2 Typical test temperatures are 40 °C for bituminous emulsions, 60 °C to 90 °C for cut-backs and fluxed bitumens, 60 °C to 200 °C for paving grade or polymer modified bituminous binders, 90°C to 230 °C for oxidized grades. For any given spindle and sample container combination, the operating instructions of the equipment shall allow the operator to select the adequate rotation speed so as to obtain a desired shear rate.

If achievable accuracy is not known from the information given by the manufacturer of the equipment, the spindles should be selected so as to obtain dynamic viscosity readings under torsion torque values which are between 10 % and 90 % of the maximum possible torsion torque of the spindle for the chosen test conditions. Whenever possible, to get a maximum of accuracy, the spindle should always be selected so as to obtain dynamic viscosity readings under torsion torque values which are in the upper working range for the chosen test conditions. For low viscosity materials (typically, for viscosities below 100 be difficult to fulfil these requirements with existing equipment. Lower accuracy is then permitted but needs to be documented while indicating, in the test report, the actually achieved level of accuracy or, if not known, the position of the reading with regard to the working range of the used spindle (Clause 10). NOTE When DSR equipment is used, neither achievable accuracy nor torsion torques ranges are known. In this case, validation of the testing conditions is done directly by the equipment software. 5.3 Sample container, specific to the rotating spindle viscometer, that allows the equipment to be used in coaxial mode and therefore enable the control of shear rate.
