Moreover, the results explained that the compatibility between PMMA and asphalt binder is improved upon further aging especially with low molecular weight polymer PMMA.

The efficiency of the stirring and the balance between heat losses and heat input must be such that the temperature of the bath medium does not vary by more than Material and Type Index Single-operator precision: The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply. Originally published as D — 63 T. Add to Cart Add to Cart. View as Grid List. See the detailed descriptions of viscometers in Annex A2 for instructions for using the type viscometer selected.

The values given in column 3 are the limits that should not be exceeded by the difference between the results of two properly conducted tests.

ASTM D2170

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. After allowing the sample to attain bath temperature see A2.


Mount the viscometer in the constant-temperature bath, keeping tube L vertical. Why is the kinematic viscosity of asphalts bitumens important to know?

ASTM D – ASTM equipment

Pour sample through tube N to a point just above filling mark G; allow the sample to flow freely through capillary R, taking care that the liquid column remains unbroken, until axtm lower meniscus is about 5 mm below the filling mark H and then arrest its flow by closing the timing tube with a cork or rubber stopper in tube L.

On the Identification of Technology Shocks: As the ice melts, drain off some of the water and add more crushed ice. This error can be as much as one or two thermometer divisions. The aging properties of polymer modified asphalts were examined using thin film oven test TFOT. The viscometer bath has a drain to remove the bath content.

Link to Active This link will always route to the current Active version of the standard. Firm supports for the viscometer shall be ast, or the viscometer may be an integral part of the bath. Historical Version s – view previous versions of standard Zstm Item s – proposed revisions of this standard Translated Version s: When thermometers are completely submerged, corrections for each individual thermometer based on calibration under conditions of complete submergence must be determined and applied.

If the sample may contain lint, solid particles, etc. Measurement of viscosity of fluids. Remove the excess sample above filling mark G by inserting the special pipet until its cork rests on top of tube N; apply gentle suction until air is drawn through. This standard has been approved for use by agencies of the Department of Defense. Add more liquid if necessary to bring the upper meniscus slightly above mark G. Select also a standard aztm of known C constant.


Unlike the modified Ostwald and suspended-level viscometers, the sample of liquid flows into a timing bulb not previously wet by sample, thus allowing the timing of liquids whose thin films are opaque.

Kinematic Viscosity ASTM D

The kinematic viscosity characterizes flow behavior. Thus, the accurate determination of viscosity is essential to many product specifications. Physical and Chemical Properties.

Documents Flashcards D210 checker. Introduce sample through tube N taking care not to asym the sides of tube N, into the cross-arm D until the leading edge stands within 0. Users should be aware that selling mercury, mercury containing products, or both, in your state may be prohibited by state law. Discard any cloudy or unsound portions.

Last previous edition D — A hot storage stability test was carried out for polymer modified binder. Introduce sufficient sample through tube N to completely fill bulb D, overflowing slightly into overflow bulb K.
